AltORF-encoded microprotein recruits primary-ORF-encoded dehydrogenase to cell poles upon heat shock

Janka J. Schmidt, Félix Ramos‐León, Aixia Zhang, Rilee Zeinert, Svetlana A. Shabalina, Gisela Storz

The paper identifies an altORF-encoded microprotein, GndA, that facilitates stress-dependent relocalization of its primary ORF partner, Gnd, in E. coli during heat shock.

A genome-wide genetic interaction platform for MRSA reveals connections between cell division and the cell envelope

Sumana Bhowmick, Félix Ramos‐León, Kumaran S. Ramamurthi, Seth W. Dickey

This study uses a dual-CRISPRi platform to map genetic interactions in MRSA, revealing connections between cell division and the cell envelope.

Orthogonal cell division organizes surface virulence factors to drive staphylococcal abscess community formation

Félix Ramos‐León, Valerie Altouma, Peri Goldberg, Amany M. Ibrahim, Domenico D’Atri, Federico Machinandiarena, Vincenzo Verdi, Dominique M. Missiakas, Kimberly Michele Davis, Kumaran S. Ramamurthi

This study shows that orthogonal cell division in Staphylococcus aureus is essential for forming abscess communities by ensuring uniform adhesin distribution and fibrin capsule assembly.
