3.5.1.98 | Co2+ | ratio of kcat to KM value in presence of metal ion in decreasing order: Co(II), Fe(II), Zn(II), Ni(II) | Homo sapiens | |
3.5.1.98 | Fe2+ | ratio of kcat to KM value in presence of metal ion in decreasing order: Co(II), Fe(II), Zn(II), Ni(II). Fe(II) bound to enzyme is readily oxidized to Fe(III) upon exposure to oxygen | Homo sapiens | |
3.5.1.98 | additional information | the identity of the catalytic metal ion influences both the Michaelis-Menten constant and the affinity of inhibitor suberoylanilide hydroxamic acid, with Fe(II) and Co(II) giving KM values 5fold lower than that of Zn(II). Apo-enzyme has a low residual level of activity | Homo sapiens | |
