| Comment(s) |
|---|
- Forms part of the peptidoglycan assembly pathway of Gram-positive
bacteria grown in medium containing D-Asp.
- Normally, the side chains the acylate the 6-amino group of the
L-lysine residue contain L-Ala-L-Ala but these amino acids are
replaced by D-Asp when D-Asp is included in the medium.
- Hybrid chains containing L-Ala-D-Asp, L-Ala-L-Ala-D-Asp or D-Asp-L-
Ala are not formed.
- Highly specific for D-aspartate, as L-aspartate, D-glutamate,
D-alanine, D-iso-asparagine and D-malic acid are not substrates.
- In Enterococcus faecium, the substrate D-aspartate is produced by
EC 5.1.1.13.
