Crystal structure of a class II UDP-glucose-hexose-1-phosphate uridylyltransferase from Bifidobacterium longum involved in human milk oligosaccharide metabolism
Infant-associated bifidobacteria utilize lacto-N-biose I (LNB) and galacto-N-biose (GNB), major components of human milk oligosaccharides and intestinal mucin, respectively, through the GNB/LNB metabolic pathway. A UDP-glucose-hexose-1-phosphate uridylyltransferase (GalT) from Bifidobacterium longum JCM 1217 (BlGalT2) catalyzes a key step in this pathway. BlGalT2 belongs to class II GalTs within…
