Arenicin
Arenicin
Arenicin (pronounced: /ɑːrɛnɪsɪn/) is a type of antimicrobial peptide that is derived from the marine polychaete worm, Arenicola marina.
Etymology
The term "Arenicin" is derived from the genus name of the marine worm from which it is isolated, Arenicola. The suffix "-in" is commonly used in biochemistry to denote a protein or peptide.
Function
Arenicin is a potent antibiotic that exhibits broad-spectrum activity against a variety of Gram-negative and Gram-positive bacteria. It functions by disrupting the bacterial cell membrane, leading to cell death.
Structure
Arenicin is a small peptide composed of 21 amino acids. It has a unique β-hairpin structure stabilized by two disulfide bridges, which is thought to contribute to its antimicrobial activity.
