Enzyme Information
| 6.1.2.1 |
D-alanine--(R)-lactate ligase.
based on mapping to UniProt P25051
D-alanine + (R)-lactate + ATP = D-alanyl-(R)-lactate + ADP + phosphate.
-!- The product of this enzyme, the depsipeptide D-alanyl-(R)-lactate, can be incorporated into the peptidoglycan pentapeptide instead of the usual D-alanyl-D-alanine dipeptide, which is formed by EC 6.3.2.4. -!- The resulting peptidoglycan does not bind the glycopeptide antibiotics vancomycin and teicoplanin, conferring resistance on the bacteria.
