From: Garvicin Q: characterization of biosynthesis and mode of action
Putative bacteriocin gene cluster of L. petauri B1726 for production of garvicin Q. The cluster consists of four genes: garQ for the pre-peptide, garI for an immunity protein, garC and garD for the transporter. The cluster contains two predicted promoters upstream of garQ and garC (indicated by arrows) and two Rho-independent transcription terminators downstream of gari and garD (indicated by lollies). Pre-garvicin Q consists of a N-terminal signal sequence (bold) with a conserved double glycine cleavage site (underlined). Pre-garvicin Q is likely processed by GarC during secretion. GarI shows similarity to an enterocin A immunity protein (PF08951). GarC contains an intracellular C39 peptidase domain (red, PF03412), an ABC-transporter transmembrane part (blue, PF00664) and an intracellular ATP-binding domain (green, PF00005). GarD contains an extracellular HlyD -typical motif (light blue, PF13437)
