WebbStructure and Biosynthesis Two natural nisinmolecules exist, termed nisin A and nisin Z. The structure of the nisin A molecule was elucidated in 1971 and is presented in Figure 1. It is a 34-amino-acid polypeptide with amino and carboxyl endgroups, and five internal ring structures involving disulfide bridges. WebbAbstract.
