Description and Uses

D-Asparagine is an isomer of L-Asparagine (A790005) and is used by bacteria (such as Saccharomyces cerevisiae) as a sole nitrogen source for replication. L-Asparagine is also a competitive inhibitor of staphylococcal L-asparaginase and is used as a reagent to synthesize peptide antibiotics.
