Glucuronidation of PhIP and N-OH-PhIP by UDP-glucuronosyltransferase 1A10.
The UDP-glucuronosyltransferase (UGT) 1A10 is an extra-hepatic enzyme that plays an important role in the glucuronidation of a variety of endogenous and exogenous substances and is expressed throughout the aerodigestive and digestive tracts. Two classes of carcinogens that target the colon, heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons, are known to be detoxified by the UGT fa...
متن کاملFunctional characterization of wild-type and variant (T202I and M59I) human UDP-glucuronosyltransferase 1A10.
UDP-glucuronosyltransferase (UGT) 1A10 is an isoform of UGT1A, which is expressed in extrahepatic, biliary and aerodigestive/gastrointestinal tissues. We have previously reported two nonsynonymous single nucleotide polymorphisms in exon 1 of human UGT1A10 gene; 177G>A and 605C>T resulting in amino acid alterations, M59I and T202I, respectively. In the present study, wild-type (WT) and these var...
متن کاملAmino acid residue ILE211 is essential for the enzymatic activity of human UDP-glucuronosyltransferase 1A10 (UGT1A10).
Conjugation of exogenous and endogenous compounds by uridine diphosphoglucuronosyltransferases (UGTs) is a pathway catalyzing the transfer of a glucuronic acid molecule from UDP glucuronic acid to lipophilic aglycones, which become more polar and more easily excretable in the bile or urine. UGTs are divided into two major families, UGT1 and UGT2. The isoform UGT1A10, along with UGT1A7 and UGT1A...
متن کاملThe first aspartic acid of the DQxD motif for human UDP-glucuronosyltransferase 1A10 interacts with UDP-glucuronic acid during catalysis.
All UDP-glucuronosyltransferase enzymes (UGTs) share a common cofactor, UDP-glucuronic acid (UDP-GlcUA). The binding site for UDP-GlcUA is localized to the C-terminal domain of UGTs on the basis of amino acid sequence homology analysis and crystal structures of glycosyltransferases, including the C-terminal domain of human UGT2B7. We hypothesized that the (393)DQMDNAK(399) region of human UGT1A...
متن کاملGastrointestinally distributed UDP-glucuronosyltransferase 1A10, which metabolizes estrogens and nonsteroidal anti-inflammatory drugs, depends upon phosphorylation.
Among gastrointestinal distributed isozymes encoded at the UGT1 locus, UDP-glucuronosyltransferase 1A10 (UGT1A10) metabolizes a number of important chemicals. Similar to broad conversion of phytoestrogens (Basu, N. K., Ciotti, M., Hwang, M. S., Kole, L., Mitra, P. S., Cho, J. W., and Owens, I. S. (2004) J. Biol. Chem. 279, 1429-1441), UGT1A10 metabolized estrogens and their derivatives, whereas...
