Purification of the peptidoglycan transglycosylase of Bacillus megaterium. 1982

A Taku, and M Stuckey, and D P Fan

The peptidoglycan transglycosylase of Bacillus megaterium has been purified approximately 500-fold from a crude membrane fraction. This protein is likely to be the one previously called PG-II and was assayed by its ability to reconstitute with a crude phospho-N-acetyl-muramyl-pentapeptide translocase preparation and partially purified N-acetylglucosaminyl transferase to give peptidoglycan synthesis from nucleotide precursors. The protein was identified as the peptidoglycan transglycosylase by its ability to synthesize lysozyme-sensitive peptidoglycan from undecaprenylpyrophosphoryl-disaccharide-pentapeptide. The enzyme is inhibited by vancomycin but not by bacitracin, penicillin G, or tunicamycin. The enzyme has no detectable transpeptidase activity, but it does bind penicillin.
