X-RAY STRUCTURE OF THE COMPLEX BETWEEN ERWINIA CHRYSANTHEMI L-ASPARAGINASE AND SUCCINIC ACID
OverviewOverview
Bacterial L-asparaginases, enzymes that catalyze the hydrolysis of, L-asparagine to aspartic acid, have been used for over 30 years as, therapeutic agents in the treatment of acute childhood lymphoblastic, leukemia. Other substrates of asparaginases include L-glutamine, D-asparagine, and succinic acid monoamide. In this report, we present, high-resolution crystal structures of the complexes of Erwinia, chrysanthemi L-asparaginase (ErA) with the products of such reactions that, also can serve as substrates, namely L-glutamic acid (L-Glu), D-aspartic, acid (D-Asp), and succinic acid (Suc). Comparison of the four independent, active sites within each complex indicates unique and specific binding of, the ligand molecules; the mode of binding is also similar between, complexes. The lack of the ... [(full description)]
