SPOR domains are approximately 70 amino acids long and occur in >1,500 proteins identified by sequencing of bacterial genomes. The SPOR domains in the FtsN cell division proteins from Escherichia coli and Caulobacter crescentus have been shown to bind peptidoglycan. Besides FtsN, E. coli has three additional SPOR domain proteins--DamX, DedD, and RlpA. We show here that all three of these proteins localize to the septal ring in E. coli. The loss of DamX or DedD either alone or in combination… CONTINUE READING
