Excited to share our new preprint on self-S-sulfonation in persulfide dioxygenase CstB from S. aureus, unveiling how it detoxifies thiol persulfides via a dynamic loop shuttle to produce thiosulfate, no sulfite released! Crystal structures, MS, & mechanistic insights included. tinyurl.com/4sr3ayz5

So happy to announce my first author publication is online @science.org! This was the culmination of two years of hard work and I couldn’t be more proud. I’m so grateful to my collaborators who helped make this possible!

The latest (and penultimate! 👀) article from the @mreniere.bsky.social lab is finally out! I’m really proud of this one in which I took a genetic approach (shocking, I know) to probe how Staph is able to grow in cystic fibrosis sputum: journals.asm.org/doi/10.1128/...

Well the award for most cowardly, boot-lickingest academic society has squarely gone to the American Society of Microbiology, who has taken down features of various non-white scientists. Absolutely pathetic behavior. Those articles are now coming up as “under review”. Truly sickening cowardice here.
