Recombinant antibacterial peptide, and preparation method and application of recombinant antibacterial peptide

Abstract

The invention belongs to the field of medicine and discloses recombinant antibacterial peptide, and a preparation method and an application of the recombinant antibacterial peptide. An amino acid sequence of the recombinant antibacterial peptide is as shown as SEQ ID NO: 1 (Sequence Identifier Number 1). The polypeptide has a better broad-spectrum antibacterial action and can be used for preparing an antibacterial medicine.

Description

technical field [0001] The invention belongs to the field of medicine and relates to a recombinant antibacterial peptide and its preparation method and application. Background technique [0002] After 200 million years of evolution, breastfeeding and its unique product, breast milk, still nourish and protect newborn babies. The large amount of protein in breast milk has an inhibitory effect on pathogenic bacteria, viruses and fungi. Some of these proteins can work alone, while others must work together. It seems that multiple components act on the same pathogenic bacteria as a kind of redundancy, but it is actually a multiple protection system. The hydrolysis of proteases in the body produces a large number of breast milk polypeptides, which not only provide amino acids as nutrition but also perform physiological functions. Further studies have found that a large number of breast milk peptides exhibit multiple antimicrobial effects and provide immune protection for newbor...
