| Other name(s): |
glutamine transaminase K; glutamine-phenylpyruvate aminotransferase |
| Systematic name: |
L-glutamine:phenylpyruvate aminotransferase |
| Comments: |
A pyridoxal-phosphate protein. L-Methionine, L-histidine and L-tyrosine can act as donors. The enzyme has little activity on pyruvate and glyoxylate (cf. EC 2.6.1.15 glutamine—pyruvate transaminase). |
