This is a family of short ~14 kDa proteins from Psuedomonas. The structure of UniProtKB:Q9HY15 a secreted protein has been solved and deposited as PDB:3npd. It comprises one structural domain with five beta-strands and five alpha-helices. Various comparative structural prediction methods plus its genomic location point to the protein forming a functional dimer with its adjacent genomic partner, UniProtKB:Q9HY14, in Pfam:PF12843. Together these might be regulated by the other product from the PotABCD operon, namely the putrescine-binding periplasmic protein UniProtKB:Q9HY16. which has been implicated in quorum-sensing. QSregVF is certainly up-regulated in quorum-sensing, and is predicted to be a virulence factor [1].	Domain
