Metabolite Identification
Common NameIsobutanol
DescriptionIsobutanol is an aliphatic alcohol. Isobutanol is a colorless, flammable, organic compound with a characteristic smell. Isobutanol is widely used in industry, as a solvent in chemical reactions, as well as being a useful starting material for organic synthesis. Isobutanol is a flammable liquid that should be stored and used in well-ventilated areas. It is moderately irritating to the skin and greatly irritating to the eyes, mucous membranes and respiratory tract. Exposure to high concentrations of its vapour can cause temporary narcosis. Isobutanol is occasionally found as a volatile component of urine and arises from gut microbial metabolism. Isobutanol is used as one of the markers to measure occupational exposure to a mixture of solvents. Aliphatic alcohols levels increase in both diabetes mellitus and insulin-dependent diabetes patients. (PMID:5556886 , 2477620 , 9143482 , 7627316 , 2288731 ). Isobutanol is a microbial metabolite found in Clostridium, Cupriavidus, Escherichia, Geobacillus, Saccharomyces and Synechococcus (PMID:19946322 ).

Enzymes

Enzyme Details
1. Serum paraoxonase/lactonase 3
General function:
Involved in arylesterase activity
Specific function:
Has low activity towards the organophosphate paraxon and aromatic carboxylic acid esters. Rapidly hydrolyzes lactones such as statin prodrugs (e.g. lovastatin). Hydrolyzes aromatic lactones and 5- or 6-member ring lactones with aliphatic substituents but not simple lactones or those with polar substituents.
Gene Name:
PON3
Uniprot ID:
Q15166
Molecular weight:
39607.185
Enzyme Details
2. Serum paraoxonase/arylesterase 1
General function:
Involved in arylesterase activity
Specific function:
Hydrolyzes the toxic metabolites of a variety of organophosphorus insecticides. Capable of hydrolyzing a broad spectrum of organophosphate substrates and lactones, and a number of aromatic carboxylic acid esters. Mediates an enzymatic protection of low density lipoproteins against oxidative modification and the consequent series of events leading to atheroma formation.
Gene Name:
PON1
Uniprot ID:
P27169
Molecular weight:
39730.99
Enzyme Details
3. Serum paraoxonase/arylesterase 2
General function:
Involved in arylesterase activity
Specific function:
Capable of hydrolyzing lactones and a number of aromatic carboxylic acid esters. Has antioxidant activity. Is not associated with high density lipoprotein. Prevents LDL lipid peroxidation, reverses the oxidation of mildly oxidized LDL, and inhibits the ability of MM-LDL to induce monocyte chemotaxis.
Gene Name:
PON2
Uniprot ID:
Q15165
Molecular weight:
39380.535
Enzyme Details
4. Intestinal-type alkaline phosphatase

Uniprot ID:
P09923
Molecular weight:
56811.695
Enzyme Details
5. Lysosomal acid phosphatase
General function:
Involved in acid phosphatase activity
Specific function:
Not Available
Gene Name:
ACP2
Uniprot ID:
P11117
Molecular weight:
48343.92
Enzyme Details
6. Alkaline phosphatase, tissue-nonspecific isozyme
General function:
Involved in catalytic activity
Specific function:
This isozyme may play a role in skeletal mineralization.
Gene Name:
ALPL
Uniprot ID:
P05186
Molecular weight:
57304.435
Enzyme Details
7. Tartrate-resistant acid phosphatase type 5
General function:
Involved in hydrolase activity
Specific function:
Involved in osteopontin/bone sialoprotein dephosphorylation. Its expression seems to increase in certain pathological states such as Gaucher and Hodgkin diseases, the hairy cell, the B-cell, and the T-cell leukemias.
Gene Name:
ACP5
Uniprot ID:
P13686
Molecular weight:
36598.47
Enzyme Details
8. Alkaline phosphatase, placental-like
General function:
Involved in catalytic activity
Specific function:
Not Available
Gene Name:
ALPPL2
Uniprot ID:
P10696
Molecular weight:
57376.515
Enzyme Details
9. Aldehyde dehydrogenase X, mitochondrial
General function:
Involved in oxidoreductase activity
Specific function:
ALDHs play a major role in the detoxification of alcohol-derived acetaldehyde. They are involved in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and lipid peroxidation.
Gene Name:
ALDH1B1
Uniprot ID:
P30837
Molecular weight:
57248.96
Enzyme Details
10. 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
