A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 5.1.1.20

Accepted Name
L-Ala-D/L-Glu epimerase.
Alternative Name(s)
AE epimerase.
Reaction catalysed
L-alanyl-D-glutamate <=> L-alanyl-L-glutamate
Comment(s)
  • The enzyme, characterized from the bacteria Escherichia coli and Bacillus subtilis, is involved in the recycling of the murein peptide, of which L-Ala-D-Glu is a component.
  • In vitro the enzyme from E.coli epimerizes several L-Ala-L-X dipeptides with broader specificity than the enzyme from B.subtilis.
  • Formerly EC 5.1.1.n1.
