Properties of Nisin

Nisin is a heat-stable and pH-stable peptide, which makes it suitable for use in a variety of food and beverage products. It is also resistant to enzymatic degradation, which increases its shelf-life and stability. The molecular weight of Nisin is around 3.5 kDa, and it is composed of 34 amino acid residues. Nisin has five amino acids that are modified by post-translational modifications, including lanthionine and methyllanthionine. These modifications increase the stability and activity of Nisin, making it a potent antimicrobial agent.
