Bacitracincomplex is a bacitracin antibiotic complex composed of cyclic dipeptides that has been found inBacillus.1It is metal-dependent and is complexed to a divalent metal cation, such as Cu2+, Ni2+, Co2+, Zn2+, or Mn2+, for its activity.1,2Bacitracincomplex is a mixture of bacitracin polypeptides in complex with copper. 1.Piacham, T., Isarankura-Na-Ayudhya, C., Nantasenamat, C., et al.Metalloantibiotic Mn(II)-bacitracincomplex mimicking manganese superoxide dismutaseBiochem.
