| aminotransferase | <enzyme> A family of enzymes that catalyse the transfer of an amino group from an alpha-amino acid to an alpha-keto acid, as in the transfer from glutamic acid to oxaloacetic acid, to form aspartic acid and alpha ketoglutarate. One reactant is often glutamic acid and the reactions employ pyridoxal phosphate as co-enzyme. (04 May 1997) |
|---|---|
| asparagine-oxo-acid aminotransferase | <enzyme> Consider also EC 2.6.1.45, serine-glyoxylate aminotransferase, which also acts on asparagine Registry number: EC 2.6.1.14 Synonym: asparagine transaminase (26 Jun 1999) |
| aspartate aminotransferase | <enzyme> An enzyme catalyzing the reversible transfer of an amine group from l-glutamic acid to oxaloacetic acid, forming alpha-ketoglutaric acid and l-aspartic acid; a diagnostic aid in viral hepatitis and in myocardial infarctions. Synonym: aspartate transaminase, glutamic-aspartic transaminase, glutamic-oxaloacetic transaminase, serum glutamic-oxaloacetic transaminase. (05 Mar 2000) |
| beta-aminoisobutyrate:pyruvate aminotransferase | Beta-aminosiobutyrate:pyruvate transaminase;an enzyme that catalyses the reversible transfer of an amino group from beta-aminoisobutyrate to pyruvate, producing l-alanine and methylmalonate saemialdehyde. A step in valine degradation. A deficiency of beta-aminoisobutyrate:pyruvate aminotransferase results in hyper-beta-aminoisobutyric aciduria. (05 Mar 2000) |
| glutamate aminotransferase | <enzyme> Aromatic keto acid acts as amine acceptor Registry number: EC 2.6.1.- (26 Jun 1999) |
| glutamine aminotransferase | <enzyme> An enzyme that reversibly converts l-glutamine, alpha-ketoglutaramate, and l-glutamate; alpha-ketoglutaramate is elevated in certain cases of hepatocoma. Synonym: glutamine transaminase. (05 Mar 2000) |
| glutamine-pyruvate aminotransferase | <enzyme> Consider also glutamine transaminase k if cysteine conjugate beta-lyase activity is also present; l-methionine can act as donor; glyoxylate can act as acceptor Registry number: EC 2.6.1.15 Synonym: glutamine alpha-ketoacid transaminase, glutamine transaminase, glutamine transaminase l, glutamine oxo-acid aminotransferase, glutaminase II, glutamine aminotransferase, l-methionine aminotransferase (26 Jun 1999) |
| glyoxylate aminotransferase | <enzyme> Various amino acids can serve as amino donors; with serine it is EC 2.6.1.45; best donors for rat liver and kidney enzyme are leucine and phenylalanine Registry number: EC 2.6.1.- (26 Jun 1999) |
| phosphoserine aminotransferase | <enzyme> Class iv aminotransferase isolated from liver Chemical name: 3-phosphoserine oxoglutarate transaminase Registry number: EC 2.6.1.52 Synonym: hydroxypyruvate-p glutamate transaminase, 3-phosphoserine aminotransferase, serc gene product (26 Jun 1999) |
| prephenate aminotransferase | <enzyme> From tobacco; forms l-arogenate (intermediate precursor of tyrosine and phenylalanine); l-aspartate and l-glutamate are only amino-donors Registry number: EC 2.6.1.- (26 Jun 1999) |
| serine-glyoxylate aminotransferase | <enzyme> Pea enzyme; also uses asparagine as amino donor with either pyruvate or glyoxylate as acceptor Registry number: EC 2.6.1.45 Synonym: asparagine aminotransferase (26 Jun 1999) |
| serine-pyruvate aminotransferase | <enzyme> Do not confuse with alanine-glyoxylate aminotransferase (EC 2.6.1.44), even though they may be products of the same gene; index whichever is discussed or both Registry number: EC 2.6.1.51 Synonym: serine aminotransferase, serine-pyruvate transaminase (26 Jun 1999) |
| hypotaurine aminotransferase | <enzyme> Converts hypotaurine to isethionate, hypothetical intermediate is sulfinoacetaldehyde Registry number: EC 2.6.1.- Synonym: 2-aminoethane sufinate aminotransferase (26 Jun 1999) |
| N(2)-succinylornithine 5-aminotransferase | <enzyme> Catalyses conversion of n(2)-succinylornithine and 2-ketoglutarate to n-succinylglutamate saemialdehyde and l-glutamate; member of catabolic arginine succinyltransferase pathway; isolated from pseudomonas aeruginosa; genbank af011922 Registry number: EC 2.6.1.- Synonym: aruc gene product, soat enzyme (26 Jun 1999) |
| diamine aminotransferase | <enzyme> Catalyses the conversion of an alpha,omega-diamine to an omega-aminoaldehyde and glutamate in the presence of 2-oxoglutarate Registry number: EC 2.6.1.29 Synonym: putrescine-alpha-ketoglutarate aminotransferase, pakg-transaminase (26 Jun 1999) |
| alanine aminotransferase |
An enzyme that is normally found in the liver cells and in the blood; an increase in ALT levels may indicate liver damage.

| alanine aminotransferase |
A liver enzyme found in the blood. Primarily produced by injured hepatocytes and is a marker of inflammation. Therefore, elevated levels of ALT usually indicate liver cell damage or necrosis (cell death). Normalization or reduction in ALT levels suggests improved liver function and a halt to disease progression.
