   1.14.20.5 | naringenin + 2-oxoglutarate + O2 |
the enzyme catalyzes the conversion of naringenin to apigenin and 2-hydroxynaringenin. It is demonstrated that the enzyme is unable to catalyze the conversion of 2-hydroxynaringenin to apigenin. It is also confirmed that 2-hydroxynaringenin cannot be an intermediate product in the conversion of naringenin to apigenin, leaving the mechanism of conversion unknown |
