| tyrosine-repressible transaminase | <enzyme> From E coli; catalyses the amination of 2-ketoisocaproate to leucine; encoded by tyrb; a functional leuabcd operon is required for leucine synthesis by this enzyme Registry number: EC 2.6.1.- Synonym: transaminase d, tyrosine-2-ketoisocaproate aminotransferase (26 Jun 1999) |

| tyrosine transaminase | <enzyme> An enzyme that catalyses the conversion of l-tyrosine and 2-oxoglutarate to 4-hydroxyphenylpyruvate and l-glutamate. It is a pyridoxal-phosphate protein. L-phenylalanine can act instead of l-tyrosine. The mitochondrial enzyme may be identical with aspartate transaminase (ec 2.6.1.1.). Chemical name: L-Tyrosine:2-oxoglutarate aminotransferase Registry number: EC 2.6.1.5 (12 Dec 1998) |
| 2,4-diaminobutyric acid transaminase | <enzyme> Catalyses conversion of l-aspartate beta-saemialdehyde to l-2,4-diaminobutyric acid Registry number: EC 2.6.1.46 Synonym: ectb gene product (26 Jun 1999) |
| 4-aminobutyrate transaminase | <enzyme> An enzyme that converts brain gamma-aminobutyric acid (gaba) into succinate saemialdehyde, which can be converted to succinic acid and enter the citric acid cycle. It also acts on beta-alanine. Chemical name: 4-Aminobutanoate:2-oxoglutarate aminotransferase Registry number: EC 2.6.1.19 (12 Dec 1998) |
