Author: William R Bishai

An allosteric inhibitor of Mycobacterium tuberculosis tryptophan synthase—an enzyme that is nonessential for in vitro growth—has potent antimicrobial activity, revealing a potentially expanded target list for antimicrobials and greater chemical space for new inhibitors.

Protein engineering: Redirecting membrane machinery

August 18th, 2017 by Kalistyn Burley

Nature Chemical Biology 13, 927 (2017). doi:10.1038/nchembio.2451

Authors: Kalistyn Burley & Celia W Goulding

The ability to solubilize membrane proteins while retaining their native function is a persistent challenge. Re-engineering of the membrane protein DsbB into a soluble cytoplasmic version maintained its activity and enabled recompartmentalization of the periplasmic DsbAB disulfide bond–forming system.

Extracellular vesicles: Taking metabolism on the road

August 18th, 2017 by Lucas B Sullivan

Extracellular vesicles (EVs) are a class of secreted membrane particles capable of transferring biological molecules between cells. Metabolomics measurements indicate that isolated EVs also have autonomous metabolic enzyme activities, including the unexpected identification of endogenous human asparaginase activity.
