Obscurin Rho GEF domains are phosphorylated by MST-family kinases but do not exhibit nucleotide exchange factor activity towards Rho GTPases in vitro

The paper investigates obscurin GEF domains, showing they are phosphorylated by MST-family kinases but lack detectable nucleotide exchange activity towards Rho GTPases in vitro.

Single-particle cryo-EM analysis of the shell architecture and internal organization of an intact α-carboxysome

This study uses single-particle cryo-EM to determine the structure of a native α-carboxysome from a marine cyanobacterium, revealing its shell architecture and internal enzyme organization.
