General description

Alanine is a non essential amino acid.

Application

D-Alanine has been used:
  • as an amine donor for ω-transaminase mediated (R)-amination
  • as a substrate for the treatment of D-amino acid oxidase (DAAO )-transfected cells
  • to measure the heat capacity of L-alanine single crystal

Biochem/physiol Actions

D-Alanine is the non-proteinogenic form of alanine which is used in bacterial cell wall biosynthesis. D-Alanine is used to study the specificity and kinetics of alanine racemase(s) (alaR).

Alanine racemase (AlaR) is a bacterial enzyme that belongs to the fold-type III group of pyridoxal 5'-phosphate (PLP)-dependent enzymes. AlaR catalyzes the interconversion between L- and D-alanine, which is important for peptidoglycan biosynthesis. This enzyme is common in prokaryotes, but

Ltnα and Ltnβ are individual components of the two-peptide lantibiotic lacticin 3147 and are unusual in that, although ribosomally synthesized, they contain d-amino acids. These result from the dehydration of l-serine to dehydroalanine by LtnM and subsequent stereospecific hydrogenation to
