  兔3-羟基己糖巴比妥脱氢酶是一种NADPH优先的还原酶，对酮类固醇，前列腺素D（2）以及其他内源性和异源性羰基化合物具有广泛的底物特异性。

  摘要：

  3-羟基己异巴比妥脱氢酶（3HBD）催化将NAD（P）（+）链接的3-羟基己异巴比妥氧化为3-羟基己异巴比妥。该酶被认为是异生物醇和某些羟基类固醇的脱氢酶，但其生理功能仍然未知。我们已经纯化了兔3HBD，分离了其cDNA，并检查了其对辅酶和底物的特异性，反应方向性和组织分布。3HBD是醛酮还原酶（AKR）超家族的成员（AKR1C29），并且在7.4的生理pH值下，NADP（H）优于NAD（H）。在与NADPH相关的还原反应中，3HBD对多种醌，酮和醛（包括3-，17-和20-酮类固醇和前列腺素D（2））显示出广泛的底物特异性，它们被转化为3alpha-，17beta-和20alpha -羟基类固醇和9alpha，11beta-前列腺素F（2），分别。特别是，α-二酮（如isatin和diacetyl）和脂质过氧化衍生的醛（如4-oxo-和4-hydroxy-2-nonenals）是显示低K（m）值（0

  A recent rat genomic sequencing predicts a gene Akr1b10 that encodes a protein with 83% sequence similarity to human aldo-keto reductase (AKR) 1B10. In this study, we isolated the cDNA for the rat AKR1B10 (R1B10) from rat brain, and examined the enzymatic properties of the recombinant protein. R1B10 utilized NADPH as the preferable coenzyme, and reduced various aldehydes (including cytotoxic 4-hydroxy-2-hexenal and 4-hydroxy- and 4-oxo-2-nonenals) and alpha-dicarbonyl compounds (such as methylglyoxal and 3-deoxyglucosone), showing low K(m) values of 0.8-6.1 mu M and 3.7-67 mu M, respectively. The enzyme also reduced glyceraldehyde and tetroses (K(m) = 96-390 mu M), although hexoses and pentoses were inactive and poor substrates, respectively. Among the substrates, 4-oxo-2-nonenal was most efficiently reduced into 4-oxo-2-nonenol, and its cytotoxicity against bovine endothelial cells was decreased by the overexpression of R1B10. R1B10 showed low sensitivity to aldose reductase inhibitors, and was activated to approximately two folds by valproic acid, and alicyclic and aromatic carboxylic acids. The mRNA for R1B10 was expressed highly in rat brain and heart, and at low levels in other rat tissues and skin fibroblasts. The results suggest that R1B10 functions as a defense system against oxidative stress and glycation in rat tissues. (C) 2010 Elsevier Inc. All rights reserved.

  for NADP(H) over NAD(H) at a physiological pH of 7.4. In the NADPH-linked reduction, 3HBD showed broad substrate specificity for a variety of quinones, ketones and aldehydes, including 3-, 17- and 20-ketosteroids and prostaglandin D(2), which were converted to 3alpha-, 17beta- and 20alpha-hydroxysteroids and 9alpha,11beta-prostaglandin F(2), respectively. Especially, alpha-diketones (such as isatin
