2.6.1.57 a

Activity

2.6.1.57

Description

Aromatic amino acid transaminase (family a)

Notes

Sequences in this family come from Gram- bacteria, and are strict homologs of aspartate aminotransferase enzymes belonging to families 2.6.1.1_a and 2.6.1.1_c.

The enzyme from E. coli was also shown to possess, in vitro, ß-methylphenylalanine transaminase activity (EC 2.6.1.107).
