    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

The enzymes correspond to type 1 3alpha-HSD (AKR1C4), type 2 3alpha(17beta)-HSD (AKR1C3), type 3 3alpha-HSD (AKR1C2) and 20alpha(3alpha)-HSD (AKR1C1), and share at least 84% amino acid sequence identity.

    In this study, we isolated the cDNA for a rabbit aldose reductase-like protein that shared an 86% sequence identity to human aldo-keto reductase (AKR)(1) 1B10 and has been assigned as AKR1B19 in the AKR superfamily. The purified recombinant AKR1B19 was similar to AKR1B10 and rabbit aldose reductase (AKR1B2) in the substrate specificity for various aldehydes and alpha-dicarbonyl compounds. In contrast to AKR1B10 and AKR1B2, AKR1B19 efficiently reduced 3-keto-5 alpha/beta-dihydro-C19/C21/C24-steroids into the corresponding 3 beta-hydroxysteroids, showing K-m of 1.3-9.1 mu M and k(cat) of 1.1-7.6 min(-1). The stereospecific reduction was also observed in the metabolism of 5 alpha- and 5 beta-dihydrotestosterones in AKR1B19-overexpressing cells. The mRNA for AKR1B19 was ubiquitously expressed in rabbit tissues, and the enzyme was co-purified with 3 beta-hydroxysteroid dehydrogenase activity from the lung. Thus, AKR1B19 may function as a 3-ketoreductase, as well as a defense system against cytotoxic carbonyl compounds in rabbit tissues. The molecular determinants for the unique 3-ketoreductase activity were investigated by replacement of Phe303 and Met304 in AKR1B19 with Gln and Ser, respectively, in AKR1B10. Single and double mutations (F303Q, M304S and F303Q/M304S) significantly impaired this activity, suggesting the two residues play critical roles in recognition of the steroidal substrate.

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.

    The structure of NaX zeolite crystals with the Se and Te atoms incorporated into the structure from their vapors has been studied. It is shown that selenium atoms form clusters in the shape of six-and four-membered rings located in the cuboctahedral cavities of the structure framework. Single Se2 molecules are located in large cavities, whereas Te atoms form four-membered rings located in cuboctahedra. Large cavities are occupied by two alternating configurations of Te atoms forming either a chain consisting of 16 links or an eight-membered ring.
