Neurohumoral Mechanisms of Cellular Aging,s a cascade of biochemical alterations that slowly progress to cell dysfunction and structural damage. While the role of AR in the pathogenesis of diabetic complications is well documented, its physiologic role, if any, under normal glycemic conditions is still unknown.

Farhan Siddiqui,Carolyn D’Ambrosiots ability to utilize NADP. to oxidize aldonic acids such as L-gulonate to D-glucuronate (Mano et al., 1961). Carbonyl reductase was first described in the 1970’s as “aromatic aldehyde and ketone reductase” by Culp and McMahon (1968). More recently, it has been referred to as carbonyl reductase (Wermuth, 1981) .

Probing the Active Site of Aldehyde Dehydrogenase by Site Directed Mutagenesisormed with either amino acid; a thiohemiacetal in the former, a hemiacetal in the latter. The intermediate would then be oxidized in the presence of NAD to produce a thioacyl or an acyl intermediate respectively, as illustrated in Fig. 1.

A Paradigm for Aldehyde Oxidation: Histidinol DehydrogenaseAlthough the latter two have important roles in health and disease, for the enzymologist HDH offers the advantage of a long and interesting genetic history, and is particularly well suited to molecular approaches.

Rat Class 3 Aldehyde Dehydrogenase: Crystals and Preliminary Analysisredictions suggest that the subunit tertiary structures of all three A1DH classes are largely similar (Lindahl and Evces, 1984; Hempel et al., 1989). Although functional residues have been identified from chemical modification and sequence comparisons, no tertiary structure of an A1DH has yet been determined.
