Abstract

The invention discloses a black sea bream antibacterial peptide AS-hepc3 (48-56) and application thereof. The molecular formula of the black sea bream antibacterial peptide AS-hepc3 (48-56) is C48H86N24O10S3, and the amino acid sequence of the black sea bream antibacterial peptide AS-hepc3 (48-56) is SEQ ID NO: 01. The antibacterial peptide AS-hepc3 (48-56) disclosed by the invention is applied asan effective component of an antibacterial drug, has the characteristics of small length, high antibacterial activity, difficulty in generating drug resistance, capability of resisting various clinical drug-resistant bacteria and the like, and has a wide prospect in the aspect of research and development of drugs for resisting drug-resistant bacteria.

Description

Technical field [0001] The invention belongs to the technical field of marine molecular biology, and specifically relates to a black sea bream antibacterial peptide AS-hepc3 (48-56) And its application. Background technique [0002] In 1928, British scientist Fleming discovered the first antibiotic-penicillin. Since then, antibiotics have been continuously discovered, improved and used in modern medicine. With the widespread use of antibiotics, antibiotic resistance is constantly being discovered. The World Health Organization's 2014 report proposed that antibiotic-resistant bacteria have spread globally, and we have entered the post-antibiotic era. At present, there are reports of antibiotic resistance worldwide, which has become one of the important issues that need to be solved urgently in the world. The WHO pointed out that at least 700,000 people die from drug-resistant diseases every year, and if effective measures are not taken, this number will reach 10 million in 2050....
