    6.3.2.4 | E15Q |
mutant enzyme with negligible depsipeptide synthetase activity. The mutant uniquely activates D-Lac as the electrophilic rather than the nucleophilic partner for condensation with D-Ala to make a regioisomeric D-Lac-D-Ala, an amide rather than an ester product |

| 6.3.2.4 | L282R |
11fold decrease in kcat for D-alanine, 18fold increase in Km for D-alanine, 23fold decrease in Km for D-serine, 9fold drop in kcat for D-serine |

9 clinical isolates that show high resistance to vancomycin have mutations in the Ddl gene, lack of growth of these mutants in the absence of vancomycin is most probably due to a complete loss of Ddl activity |
