title: Ubericin A, a class IIa bacteriocin produced by Streptococcus uberis.
abstract: Streptococcus uberis, a causal agent of bovine mastitis, produces ubericin A, a 5.3-kDa class IIa (pediocin-like) bacteriocin, which was purified and characterized. The uba locus comprises two overlapping genes: ubaA (ubericin A precursor peptide) and ubaI (putative immunity protein). Ubericin A is the first streptococcal class IIa bacteriocin to be characterized.
