Several PLP-dependent enzymes (mainly aminotransferases) show this activity, possibly as a side reaction.
In the public databases, sequences explicitly associated with this function also show kynurenine aminotransferase (EC 2.6.1.7) and glutamine-phenylpyruvate transaminase (EC 2.6.1.64) activities. These sequences have been included in the 2.6.1.7 family. |
