Metabolite Identification
Common Name2-Phenylpropionate
Description2-Phenylpropionate is an intermediate in alpha-Methylstyrene (2-phenylpropylene) metabolism. It was identified in human liver slices in small amounts. It is. likely that 2-Phenylpropionate derives from 2-phenylpropionaldehyde, formed from a. 1,2-hydride shift during the transfer of active oxygen to the vinyl. group, as has been proposed for the cytochrome P450-mediated oxidation. of styrene to form phenylacetaldehyde. (PMID: 11159807 ). 2-Phenylpropionate has been found to be a metabolite of Acinetobacter, Bacteroides, Bifidobacterium, Clostridium, Enterococcus, Escherichia, Eubacterium, Klebsiella, Lactobacillus, Pseudomonas and Staphylococcus (PMID: 19961416 ).

Enzymes

General function:
Involved in transferase activity, transferring hexosyl groups
Specific function:
UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.
