Abstract

The Gram-positive bacterium Bacillus subtilis has a thick cell wall. The cell wall contains various proteins, both for secretion and for peptidoglycan (PG) maintenance. Penicillin-binding proteins for PG synthesis, PG hydrolases (autolysins), and regulator proteins for the autolysins are the known components of the PG maintenance system. YqgA was identified as an abundant protein attached to the cell wall of B. subtilis through a proteomics analysis. The YqgA protein was localized at cell division sites during the transition period between the exponential and the stationary phases. YqgA localization was affected by mutations in the DL-endopeptidases (DLEPases), which are the autolysins involved in cell morphogenesis. Furthermore, yqgA mutations on a background of defective DLEPases led to delays in cell growth and cell morphological changes. These results demonstrate that yqgA is genetically related to the genes encoding DLEPases involved in cell morphogenesis.
