Latest from the lab! Analysis of everyone’s favorite regulatory mechanism in bacteria — the RF2 programmed frameshift! Likely present in the ancestor of bacteria, use of this mechanism is influenced by stop codon usage! Big congrats to @cassidyprints.bsky.social

Conservation and evolution of the programmed ribosomal frameshift in prfB across the bacterial domain | mBio

Translation termination is catalyzed by one of two release factors in bacteria, RF1 or RF2. It has been known for decades that RF2 levels in Escherichia coli are regulated by a programmed ribosomal frameshift within the prfB gene that encodes RF2. We ...

I left this geranium for dead last spring in a window sill and suddenly this morning I notice one green leaf and one tiny pink flower. That’s hope y’all.

I am very happy to share that I have started this week as an Assistant Professor of Microbiology at the Richard A. Gillespie College of Veterinary Medicine in Harrogate, Tennessee. It has been a beautiful journey from IAAS to Ohio State to Cornell, and now to LMU-CVM.

Check out our new paper: a review of translational coupling, the phenomenon where translation of one prokaryotic gene can promote translation of the gene downstream. We cover the history, and delve into the mechanism, which is still not fully understood. journals.asm.org/doi/10.1128/...

Translational coupling of neighboring genes in prokaryotes | Journal of Bacteriology

Prokaryotic genes are arranged in operons, with functionally related genes often located adjacent to one another (1). There are several ways in which the operonic organization of genes facilitates the...
