what secretes bacitracin
Bacitracin is very different than penicillins and cephalosporins, but it still inhibits peptidoglycan synthesis. It is a polypeptide antibiotic derived from a Bacillus bacterium found in a wound on a girl named Tracy. That's how it got its name.Bacitracin inhibits peptidoglycan synthesis at an earlier step than the penicillins and cephalosporins. It inhibits the synthesis of the linear strands of NAG and NAM, two sugars that make up the major part of the peptidoglycan matrix.Bacitracin also works best against Gram-positive organisms.hat's how it got its name.
