Gelatinase biosynthesis-activating pheromone abbreviated as GBAP is a cyclic peptide produced by pathogenic bacteria such as Enterococcus faecalis. [1] GAP is part of the quorum sensing system of certain bacteria where it positively regulates the expression of gelatinase and serine proteases that are under the control of the gelE-sprE operon. [2]
GBAP is an 11-amino-acid-residue cyclic peptide containing a lactone linkage between the C-terminal carboxylic acid group and a serine side chain hydroxyl group. [2]
