Accepted name: D-Ala-D-Ala dipeptidase
Reaction: D-Ala-D-Ala + H2O = 2 D-Ala
Other name(s): D-alanyl-D-alanine dipeptidase; vanX D-Ala-D-Ala dipeptidase; VanX
Comments: A Zn2+-dependent enzyme [4]. The enzyme protects Enterococcus faecium from the antibiotic vancomycin, which can bind to the -D-Ala-D-Ala sequence at the C-terminus of the peptidoglycan pentapeptide (see diagram). This enzyme reduces the availability of the free dipeptide D-Ala-D-Ala, which is the precursor for this pentapeptide sequence, allowing D-Ala-(R)-lactate (for which vancomycin has much less affinity) to be added to the cell wall instead [2,3]. The enzyme is stereospecific, as L-Ala-L-Ala, D-Ala-L-Ala and L-Ala-D-Ala are not substrates [2]. Belongs in peptidase family M15.

Systematic name: a [protein]-L-amino acid-1-hydroxypropan-2-one hydrolase [(R)-lactate-forming]
Comments: The enzyme, previously thought to be a glyoxalase, acts on glycated L-arginine, L-lysine, and L-cysteine residues within proteins that have been attacked and modified by glyoxal or 2-oxopropanal. The attack forms hemithioacetal in the case of cysteines and aminocarbinols in the case of arginines and lysines. The enzyme repairs the amino acids, releasing glycolate or lactate (70-80% (S)-lactate and 20-30% (R)-lactate), depending on whether the attacking agent was glyoxal or 2-oxopropanal, respectively [3,4].

Other name(s): glyoxylase III; GLO3

Accepted name: D-alanine—(R)-lactate ligase
Reaction: D-alanine + (R)-lactate + ATP = D-alanyl-(R)-lactate + ADP + phosphate
Glossary: (R)-lactate = D-lactate
D-alanyl-(R)-lactate = D-alanyl-D-lactate = (2R)-2-(D-alanyloxy)propanoic acid = (R)-2-((R)-2-aminopropanoyloxy)propanoic acid
