'''ATOMIC X-RAY STRUCTURE OF LIVER ALCOHOL DEHYDROGENASE CONTAINING A HYDROXIDE ADDUCT TO NADH'''<br />


==Overview==
==atomic X-ray structure of liver alcohol dehydrogenase containing a hydroxide adduct to NADH==
Atomic (1 A) resolution x-ray structures of horse liver alcohol, dehydrogenase in complex with NADH revealed the formation of an adduct in, the active site between a metal-bound water and NADH. Furthermore, a, pronounced distortion of the pyridine ring of NADH was observed. A series, of quantum chemical calculations on the water-nicotinamide adduct showed, that the puckering of the pyridine ring in the crystal structures can only, be reproduced when the water is considered a hydroxide ion. These, observations provide fundamental insight into the enzymatic activation of, NADH for hydride transfer.

== Publication Abstract from PubMed ==
Atomic (1 A) resolution x-ray structures of horse liver alcohol dehydrogenase in complex with NADH revealed the formation of an adduct in the active site between a metal-bound water and NADH. Furthermore, a pronounced distortion of the pyridine ring of NADH was observed. A series of quantum chemical calculations on the water-nicotinamide adduct showed that the puckering of the pyridine ring in the crystal structures can only be reproduced when the water is considered a hydroxide ion. These observations provide fundamental insight into the enzymatic activation of NADH for hydride transfer.
