Introduction of 2058-58-4 :

D-Asparagine (H-D-Asn-OH) acts as a competitive inhibitor of L-asparagine hydrolysis, with a Ki value of 0.24 mM. D-Asparagine serves as a nitrogen source for yeast strains. D-Asparagine is a good substrate for external yeast asparaginase but a poor substrate for internal yeast asparaginase[1][2]. In Vitro:D-Asparagine (2-10 mM; 48 h, generation time measured at 21°C) can serve as the sole nitrogen source for growth in extracellular asparaginase-secreting Saccharomyces cerevisiae strains (D273-10B, X2180-A2) and their gap-1 mutants[1].
