Howell lab deduces the mechanism of type IV pilus motors

5 May 2017|0 Comments

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 […]

Houry lab identifies a novel regulator of respiratory chain complexes

13 February 2017|0 Comments

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, […]
