Metabolite Identification

Common Name

2-Methyl-3-hydroxybutyric acid

Description

3-Hydroxy-2-methyl-butanoic acid (HMBA) is a normal urinary metabolite involved in the isoleucine catabolism, as well as presumably beta-oxidation of fatty acids and ketogenesis, excreted in abnormally high amounts in beta-ketothiolase deficiency, which is a genetic disorder. Differences in the enantiomeric ratio of HMBA may originate from the enantioselectivity of different enzyme systems (PMID 10755375 ).

Enzymes

Enzyme Details

1. Sulfotransferase family cytosolic 2B member 1

General function:: Involved in sulfotransferase activity
Specific function:: Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of many hormones, neurotransmitters, drugs and xenobiotic compounds. Sulfonation increases the water solubility of most compounds, and therefore their renal excretion, but it can also result in bioactivation to form active metabolites. Sulfates hydroxysteroids like DHEA. Isoform 1 preferentially sulfonates cholesterol, and isoform 2 avidly sulfonates pregnenolone but not cholesterol.
Gene Name:: SULT2B1
Uniprot ID:: O00204
Molecular weight:: 39598.595

Reactions

2-Methyl-3-hydroxybutyric acid → 2-methyl-3-(sulfooxy)butanoic acid	details

Enzyme Details

2. UDP-glucuronosyltransferase 1-1

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.
