Description |
Branched chain amino acid--pyruvate transaminase (low-specificity) (2.6.1.-) |
Alternative names |
TUZN1299 (gene name);
VMUT0738 (gene name); |
Catalyzed reaction |
4-methyl-2-oxovalerate+alanine = leucine+ pyruvate |
Cofactor |
Pyridoxal-phosphate |
|
TUZN1299 was found to be highly active toward branched-chain amino acids (BCAAs), positively charged amino acids, l-methionine, l-threonine, l-homoserine, l-glutamine, as well as toward 2-oxobutyrate and keto analogs of BCAAs, whereas l-glutamate and α-ketoglutarate were not converted in the overall reaction. (This is a striking difference with respect to classic BCAATs, grouped in family 2.6.1.42_a) |
