Abstract

Depletion of the B. subtilis GTPase CpgA produces abnormal cell shapes, non-uniform deposition of cell wall and 5-6 fold accumulation of peptidoglycan precursors. Nevertheless, the inherent structure of the cell wall appeared mostly unchanged. The results are consistent with CpgA being involved in coordinating normal peptidoglycan deposition.
