Max’s paper describing the Zn(II) coordination chemistry, G-nucleotide-induced folding and extensive hydrogen-deuterium exchange-mass spectrometry (HDX-MS) of the bacterial COG0523 enzyme, Acinetobacter baumannii ZigA, is accepted today in Biophysical Journal. Happy birthday Max! Congratulations also to our collaborators Tim Stemmler (Wayne State) and Daniel Deredge (University of Maryland Baltimore).

The Capdevila, Giedroc and Dalia groups have published the first study on persulfide sensing and thiol persulfide profiling in the gut pathogen, Vibrio cholerae. A comprehensive sequence similarity network (SSN) analysis of arsenic repressor (ArsR) superfamily is also reported here, which will be very useful to others in the field.  Congratulations to Daiana and members of her team (Cristian and Giuliano) for driving this work to completion.

We seek a postdoctoral research associate to join an engaging multidisciplinary team of students and staff working to understand the bacterial metabolic response to infected host-mediated restriction of essential transition metal ions!  The successful candidate will conduct structural and mechanistic studies of the human COG0523 family zinc metallochaperone, ZNG1, alongside ongoing work on bacterial metallochaperones.

Interested candidates can apply here or simply submit a brief cover letter, full CV and the contact information for three letter writers to David P. Giedroc, Department of Chemistry, Indiana University, 800 E. Kirkwood Ave., Bloomington, IN 47405-7102 USA ( For best consideration, apply by 10/01/2023, with a start date of 12/01/2023 or thereabouts!
