Mutants, suppressors, and wrinkled colonies: mutant alleles of the cell division gene ftsQ point to functional domains in FtsQ and a role for domain 1C of FtsA in divisome assembly.

Abstract excerpt

Cell division in Escherichia coli requires the concerted action of at least 10 essential proteins. One of these proteins, FtsQ, is physically associated with multiple essential division proteins, including FtsK, FtsL, FtsB, FtsW, and FtsI. In this work we performed a genetic analysis of the ftsQ gene. Our studies identified C-terminal residues essential for FtsQ's interaction with two downstream proteins, FtsL...
