The hyperthermophilic bacterium Thermotoga maritima contains a peptidoglycan comprising D-alanine, D-glutamate, and D-lysine. We have previously identified the biosynthetic pathways of D-lysine and D-glutamate; however, the biosynthetic pathway of D-alanine is unclear in T. maritima. The present study elucidated the D-...

The difructose dianhydride I synthase/hydrolase α FFase 1 catalyzes the reversible transformation of inulobiose into difructose dianhydride I, a component of caramel. The proposed reaction mechanism of such a transformation consists of a glycosylation step followed by a cyclization to yield the dianhydride from the dis...

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)...
