Research Abstract

YbiS and its paralogs, ErfK and YcfS, that are periplasmic proteins of Escherichia coli were biochemically and genetically identified as transpeptidases (TPase) to bind covalently lipoproteins to peptidoglycan. The result that YbiS and YcfS function acid-neutral and alkali conditions, respectively, strongly suggest that these TPase cooperatively work to adapt to the environmental change.
