The ponA gene of Mycobacterium smegmatis
encodes a 95-kDa penicillin binding protein, PBP1, that is similar to
PBP1s of Mycobacterium tuberculosis and Mycobacterium
leprae. Transposon disruption of ponA in M. smegmatis resulted in a PBP1-deficient mutant that was sensitive
to
-lactam antibiotics, was more permeable to glycine, and grew
slowly in liquid culture.
