Malacidin B, along with [DB14051], is a member of a class of chemicals made by bacteria found in soil that can kill Gram-positive bacteria. Malacidins are 10-member macrocycle lipopeptides discovered via gene sequencing and bioinformatic analysis. While structurally similar to other macrocycle drugs like [DB00080] and [DB06087], Malacidin B appears to act via its own distinct mechanism.
