Metabolite Identification
Common Name2-Hydroxy-3-methylbutyric acid
Description2-Hydroxy-3-methylbutyric acid (also known as 2-hydroxyisovaleric acid) is a metabolite found in the urine of patients with phenylketonuria (PMID: 7978272 ), methylmalonic acidemia, propionic acidemia, 3-ketothiolase deficiency, isovaleric acidemia, 3-methylcrotonylglycemia, 3-hydroxy-3-methylglutaric acidemia, multiple carboxylase deficiency, glutaric aciduria, ornithine transcarbamylase deficiency, glyceroluria, tyrosinemia type I, galactosemia, and maple syrup urine disease (PMID: 11048741 ). 2-Hydroxyisovaleric acid has also been identified in the urine of patients with lactic acidosis and ketoacidosis (PMID: 884872 ), and in the urine of severely asphyxiated babies (PMID: 1610944 ). 2-Hydroxyisovaleric acid originates mainly from ketogenesis and from the metabolism of valine, leucine, and isoleucine (PMID: 6434570 ). 2-Hydroxy-3-methylbutyric acid has been identified in the human placenta (PMID: 32033212 ).

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-Hydroxy-3-methylbutyric acid → 3-methyl-2-(sulfooxy)butanoic aciddetails
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.
Gene Name:
UGT1A1
Uniprot ID:
P22309
