d-Serine (d-Ser) is a coagonist for NMDA-type glutamate receptors and is thus important for higher brain function. d-Ser is synthesized by serine racemase and degraded by d-amino acid oxidase. However, the significance of these enzymes and the releva

The hyperthermophilic bacterium Thermotoga maritima has an atypical peptidoglycan that contains d-lysine alongside the usual d-alanine and d-glutamate. We previously identified a lysine racemase involved in d-lysine biosynthesis, and this enzyme also

The peptidoglycan of the hyperthermophile Thermotoga maritima contains an unusual component, d-lysine (d-Lys), in addition to the typical d-alanine (d-Ala) and d-glutamate (d-Glu). In a previous study, we identified a Lys racemase that is presumably

The free d-amino acid, d-aspartate, is abundant in the embryonic brain but significantly decreases after birth. Besides its intracellular occurrence, d-aspartate is also present at extracellular level and acts as an endogenous agonist for NMDA and mG
