Nisin 是乳酸链球菌肽，由一组属于乳球菌和链球菌属的革兰氏阳性菌产生。

Nisin A is an antibacterial peptide. It is produced by the lactic acid bacterium L. lactis using uncommon amino acids, including lanthionine, and is a member of the class of antibiotics referred to as lantibiotics.

Nisin is classified as a Type A (I) lantibiotic that is synthesized from mRNA and the translated peptide contains several unusual amino acids due to post-translational modifications. Nisin is an antimicrobial peptide produced by certain Gram-positive bacteria which include Lactococcus and Streptococcus species[1].
