ID 5.1.1.20 DE L-Ala-D/L-Glu epimerase. AN AE epimerase. CA L-alanyl-L-glutamate = L-alanyl-D-glutamate. CC -!- The enzyme, characterized from the bacteria Escherichia coli and CC Bacillus subtilis, is involved in the recycling of the murein CC peptide, of which L-Ala-D-Glu is a component. CC -!- In vitro the enzyme from E.coli epimerizes several L-Ala-L-X CC dipeptides with broader specificity than the enzyme from B.subtilis. CC -!- Formerly EC 5.1.1.n1.
