CRYSTAL STRUCTURE OF SULA:FTSZ FROM PSEUDOMONAS AERUGINOSA
Overview
SulA halts cell division in Escherichia coli by binding to the major, component of the division machinery FtsZ. We have solved the crystal, structure of SulA alone and in complex with FtsZ from Pseudomonas, aeruginosa. SulA is expressed when the SOS response is induced. This is a, mechanism to inhibit cell division and repair DNA in the event of DNA, damage. FtsZ is a tubulin-like protein that forms polymers, with the, active-site GTPase split across two monomers. One monomer provides the, GTP-binding site and the other, through its T7 loop nucleotide hydrolysis., Our structures show that SulA is a dimer, and that SulA inhibits cell, division neither by binding the nucleotide-binding site nor by inducing, conformational changes in FtsZ. Instead, SulA binds the T7 loop surface of, FtsZ, ... [(full description)]
