Howell lab deduces the mechanism of type IV pilus motors

5 May 2017|

Howell lab

The type IV pilus is a long and sturdy grappling hook that bacteria use to attach to a surface and then pull themselves closer to the surface. They are important for virulence in many pathogens, including those that cause cholera, gonorrhoea, food-borne diseases, and multi-drug resistant hospital acquired infections. The molecular mechanism of the motors involved in throwing out and pulling […]

New genetic disease discovered by Drs. Aleixo Muise and Walter Kahr

7 April 2017|

Two of Biochemistry’s professors, Drs. Aleixo Muise and Walter Kahr have discovered a brand new genetic disease through their research at the Hospital for Sick Children.

Their research article is published on Nature Communications.

Their story was also highlighted on the Hospital for Sick Children, CBC The National and CBC News Network, and the Globe and Mail websites:

Visual and Interactive Media for Deeper Molecular Understanding of Enzyme Kinetics

3 April 2017|

Dr. Stavroula Andreopoulos and Dr. Derek Ng were awarded a 2017-2019 Elevation Grant from the Advancing Teaching and Learning in Arts & Science (ATLAS) initiatives fund. The proposal “Visual and Interactive Media for Deeper Molecular Understanding of Enzyme Kinetics” represents the start of a long-term mutually beneficial collaboration between the Department of Biochemistry and UTM’s Biomedical Communications (BMC) program. MScBMC students will design and develop a […]

Professor Lewis Kay.

Dr. Lewis Kay named a 2017 Canada Gairdner International Award Laureate!

30 March 2017|

Congratulatory message from the Chair

On behalf of the entire Biochemistry Department I would like to congratulate our esteemed colleague Dr. Lewis Kay on winning the Gairdner International Award, Canada’s highest science prize. Kay’s work on the development and use of nuclear magnetic resonance (NMR) techniques for investigating molecular motion and short lived conformations in large multiprotein complexes, or ‘seeing the unseeable’ to use the vernacular, has pushed boundaries […]

Houry lab identifies a novel regulator of respiratory chain complexes

13 February 2017|

Graphical abstract_120616

An interaction between the respiratory enzyme fumarate reductase (Frd, also known as Complex II) and an ATPase has been identified in E. coli by the Houry lab. The research shows that the RavA ATPase, belonging to a poorly characterized but ubiquitous MoxR family of AAA+ ATPases, associates with the Frd respiratory enzyme through an adaptor, which the group named ViaA. […]

Ernst Lab discover new way to crystallize membrane proteins

7 February 2017|

The laboratory of Dr. Oliver Ernst has used X-ray crystallography to determine the structure of a membrane protein that never left a lipid-bilayer environment (i.e., without the use of conventional detergents). The work, published in Structure and highlighted on the Journal’s cover, was led by postdoctoral fellow Dr. Jana Broecker. Polymer-bounded lipid nanodiscs were used to extract and purify membrane proteins with their surrounding lipids and allowed […]

After release into the host cell, translocated bacterial substrates (effectors) regulate one another through several different functional interactions: indirectly, through counteracting modification of a shared host target, or directly through either steric complex formation or direct modification of one effector by another.

Ensminger lab discovers a class of bacterial effectors with novel regulatory activities

3 February 2017|

Many bacterial pathogens modulate their hosts through complex arsenals of effector proteins that are injected into host cell during infection. Indeed, the concept that effectors target host proteins and processes to modulate their activities is central to the current molecular understanding of host-pathogen interactions. Legionella pneumophila, the causative agent of a deadly pneumonia known as Legionnaires’ disease, has over 300 effectors, which is the largest known arsenal amongst bacterial pathogens. […]
