'''Structure of the MT-ADPRase in complex with gadolidium and ADP-ribose, a Nudix enzyme'''<br />


==Overview==
==Structure of the MT-ADPRase in complex with gadolidium and ADP-ribose, a Nudix enzyme==
Nudix hydrolases are a family of proteins that contain the characteristic, sequence GX(5)EX(7)REUXEEXG(I/L/V), the Nudix box. They catalyze the, hydrolysis of a variety of nucleoside diphosphate derivatives such as, ADP-ribose, Ap(n)A (3 &lt;/= n &lt;/= 6), NADH, and dATP. A number of Nudix, hydrolases from several species, ranging from bacteria to humans, have, been characterized, including, in some cases, the determination of their, three-dimensional structures. The product of the Rv1700 gene of M., tuberculosis is a Nudix hydrolase specific for ADP-ribose (ADPR). We have, determined the crystal structures of MT-ADPRase alone, and in complex with, substrate, with substrate and the nonactivating metal ion Gd(3+), and in, complex with a nonhydrolyzable ADPR analog and the activating metal ion, Mn(2+). These structures, refined with data extending to resolutions, between 2.0 and 2.3 A, showed that there are sequence differences in, binding site residues between MT-ADPRase and a human homolog that may be, exploited for antituberculosis drug development.
