Function
LNPA_BIFL2 Reversibly phosphorolyzes lacto-N-biose to Gal1-P and N-acetylglucosamine (GlcNAc) and galacto-N-biose to Gal1-P and N-acetylgalactosamine (GalNAc). Involved in the lacto-N-biose I/galacto-N-biose (LNB/GNB) degradation pathway, which is important for host intestinal colonization by bifidobacteria.[1] [2] [3]
