• Description:
  Mannose phosphotransferase system (Man-PTS) is the main mannose permease in bacteria but it is also a known receptor for subclass IIa bacteriocins (pediocin-like group) as well as subclass IId lactococcin A (LcnA) and lactococcin B (LcnB) (LcnA-like group). Subclass IIa bacteriocins exhibit a strong activity against Listeria spp. but they are not against Lactococcus spp. In contrast, the LcnA-like bacteriocins act only against Lactococcus lactis strains. Garvicin Q (GarQ) is a subclass IId bacteriocin with minor similarity to LcnA-like bacteriocins and a relatively broad antimicrobial spectrum including, among others, Listeria and Lactococcus spp. To identify the GarQ receptor, we obtained GarQ-resistant mutants of Lactococcus garvieae IBB3403 and L. lactis IL1403 and sequenced their genomes that revealed mutations in genes encoding the membrane-bound Man-PTS IIC or IID subunits encoded by ptnCD in L. lactis and manCD in L. garvieae. This is the first time that a bacteriocin outside the pediocin- and LcnA-like groups is shown to target Man-PTS. The interaction between GarQ and Man-PTS may occur through a new binding pattern involving specific amino acids highly conserved among the GarQ-sensitive bacterial species located in the N-terminal part and extracellular loops of subunit IID and in transmembrane region of IIC.
