Biological Activity

[Description]:

D-Asparagine (H-D-Asn-OH) is a competitive inhibitor of L-Asparagine hydrolysis with a Ki value of 0.24 mM. D-Asparagine is a source of nitrogen for yeast strains. D-Asparagine is a good substrate for the external yeast asparaginase but is a poor substrate for the internal enzyme[1].

In several cell types tumour suppressor p53 induces apoptosis largely via Puma but Noxa can contribute.

Cell Death Differ. 15(6) , 1019-29, (2008)

The ability of p53 to induce apoptosis in cells with damaged DNA is thought to contribute greatly to its tumour suppressor function. P53 has been proposed to induce apoptosis via numerous transcriptio...
