Description: | Pulcherriminic acid is a cyclic dipeptide antimicrobial agent with high affinity for Fe3+, found mainly in Bacillus and yeast. Pulcherriminic acid chelates iron ions through a non-enzymatic reaction to form the extracellular red pigment pulcherrimin, which competes for iron nutrition and thus achieves an antibacterial effect. Pulcherriminic acid has great applications in food, agriculture and medical industries[1][2]. |
