CLS opens special Call for Proposals
March 23, 2020
The CLS is currently in standby mode until the facility is once again able to safely open, pursuant to local government guidance. A Special Call for Proposals is now open for work that will actively contribute to finding COVID-related treatments. Please see the following website for additional information and instructions for submitting a proposal:CLS COVID-19 Call for Proposals Information about measures being taken by the CLS to deal with the current situation is available here.Resources at other facilities have also become available for researchers wishing to access remote beam time for urgent research related to COVID-19. The following facilities are currently accepting proposals for such work:-  Advanced Photon Source-  ALBA Synchrotron-  BESSY II at HZB-  Diamond Light Source-  Elettra Sincrotrone Trieste-  European Synchrotron Radiation Faclity-  MAX IV-  National Synchrotron Light Source II-  Petra III at DESY-  Stanford Synchrotron Radiation Lightsource-  Swiss Light SourceWe endeavour to maintain an updated list for the convenience of our users.

More samples, more problems!
Jan. 14, 2019
Over the past years, the CMCF has invested in over 100 Uni-Pucks to facilitate introduction of efficient automated methods that allow Remote Control, with significant time and cost-savings from reduced travel. The equipment facilitates bringing new User Groups into the life of the facility and is used heavily for the annual CLS Mx Data Collection School. We hope to continue having loaner Uni-Pucks and tools available for those who may occasionally need extra equipment, and to support the introduction of new research groups.At the moment, the CMCF has no more loaner Uni-Pucks available. If your group has been considering the purchase of dedicated Uni-Pucks and tools, it would be an ideal time for CLS Uni-Pucks that are being replaced to be returned to the CMCF for the benefit of the community.Please feel free to contact us for advice on purchasing Uni-Pucks or other equipment. There is information along with links to suppliers on the CMCF Samples & Automounters page. We hope that the availability of the loaner equipment has served CMCF Users well and we hope to be able to continue this tradition!

Shut-down extended until January 2019...
Sept. 28, 2018
On June 27, the facility's electron source failed, resulting in loss of beam. Several malfunctioning components were identified in the main electron gun’s power supply. After initial repairs, CLS staff members determined that the power supply’s transformer needed to be replaced. We regret the impact this outage will have on affected projects, and CLS staff are doing everything possible to resolve the problem. In order to complete the repairs, the CLS has had to cancel user shifts until January 2019.Link to CLS information page

Exploring how coronavirus adapts to new situations...
July 27, 2018
Coronavirus spike protein mediates receptor binding and fusion of viral and host cell membranes. Results from this project provide a model for coronavirus adaptation to environmental changes based on the use of three extended loops for receptor binding, with such loop regions being inherently accommodating to mutational changes. Given their wide host range and zoonotic transmission to humans, coronavirus provides an important model for studying RNA viruses and emergence of new viral threats.PDB ID 6ATK.

2016 marks 10th anniversary of first crystal diffraction experiment at CMCF... click title for details!
Oct. 24, 2016
In 1999, the Canadian crystallography community submitted a proposal to the Canadian Light Source (CLS) to build the first crystallography beamline in Canada. This beamline, together with staff and infrastructure, was to be called the Canadian Macromolecular Crystallography Facility (CMCF). In 2005, thanks to the talent and dedication of CLS employees, construction of beamline 08ID-1 was completed. That same year, construction of a second crystallography beamline, 08B1-1, began and was completed in 2009. In 2011, this beamline saw its first remote experiments.In 2006, ten years ago, the first CMCF experiment was performed. The structure depicted (PDB ID 2i1q) is from the article published with the resulting data (J. Biol. Chem. 281, 39380-7), and represents the structure of RadA recombinase in complex with calcium. This protein plays a critical role in DNA repair. Since the first CMCF experiment in 2006, the CLS has become a hub of activity for Canadian crystallographers, supporting the work of the majority of the nation’s crystallography laboratories and several international researchers. The number of publications resulting from the work of dedicated researchers using the facility has risen steadily since its inception, with over 425 peer reviewed articles, 800 structures deposited in the Protein Data Bank and several patents and dissertations.As time advances, so do the needs of the crystallography community. To this end, several exciting upgrades are being implemented. The beamlines’ goals include higher flux on both beamlines, micro-beam capabilities as well as much faster data collection and sample transfer times in order to meet tomorrow’s challenges. The CMCF sincerely thanks all of the dedicated researchers, CLS staff, Beamline Advisory Team and funding agencies for their constant and unwavering support.

Dr. Michelle (Tonkin) Parker presented with G. Michael Bancroft Ph.D. Thesis Award at this year's AUM.
July 2, 2015
At this year's Annual Users Meeting, Dr. Michelle (Tonkin) Parker was recognized with the G. Michael Bancroft Ph.D. Thesis Award. Michelle completed her doctoral work, entitled "Molecular Strategies for Active Host Cell Invasion by Apicomplexan Parasites", as a graduate student in Prof. Martin Boulanger's research group at the University of Victoria. During her studies, she published several papers related to the mechanism of malarial infections. New methods to combat malaria have become increasingly important as these parasites develop resistance to available drugs. Through collaborations with groups working on malaria drug and vaccine initiatives, Michelle's results have the potential to aid the development of novel treatment strategies.Link to related CLS story

Structure of a sodium channel inactivation gate in complex with calcium-bound calmodulin.
March 7, 2012
Properly-functioning voltage-gated sodium channels are critical to the normal contraction and relaxation of heart muscle cells. Calcium ions bound to another protein called calmodulin can modulate these channels. Researchers have used data obtained at the CMCF to solve the 1.35 Å structure of calcium-bound calmodulin in complex with the inactivation gate of a sodium channel. Several mutations near the calmodulin binding site have been identified which result in arrhythmias or other physiological problems. View the full CLS press release here.Proc. Natl. Acad. Sci.

MxLIVE (Mx Laboratory Information Virtual Environment) is the CMCF Laboratory Information Management System that will help your lab organize samples, shipments and experimental information to integrate your lab with data collection at the beamlines. When MxLIVE is used in conjunction with the MxDC data collection software, members of your team not at the beamline can easily check on the progress of experiments taking place at the beamlines and even view diffraction images through a secure web server. MxLIVE also helps you organize all of your crystal samples, information about their properties and contents, experimental parameters that you want to use for data collection, screening results and experimental results! An invaluable tool whether you are collecting data at the beamlines, collecting data remotely or sending samples for Mail-In data collection.

March 2, 2011
Researchers from Dr. Emil Pai's laboratory at the Ontario Cancer Institute were the first to benefit from the remote control capabilities that recently became available on beamline 08B1-1. This mode of operation allows researchers to collect data as though they were present at the beamline without leaving their home laboratories, thereby saving costs associated with travel. The researchers shipped their samples in standard containers which were loaded into the robotic automounter by beamline staff. Using a freely-available software client installed on their laboratory computers, the research team was able to connect to the beamline through a secure encrypted channel in order to perform their experiments with minimal intervention by beamline staff. Remote control is available on beamline 08B1-1 to users with an active proposal after completing appropriate training. Users wishing to use this capability should contact beamline staff.
