Co2+ | activity follows the trend Fe2+>Co2+>Zn2+>Mn2+ and Ni2+ | Mycolicibacterium smegmatis | |
Fe2+ | activity follows the trend Fe2+>Co2+>Zn2+>Mn2+ and Ni2+ | Mycolicibacterium smegmatis | |
Mn2+ | activity follows the trend Fe2+>Co2+>Zn2+>Mn2+ and Ni2+ | Mycolicibacterium smegmatis | |
additional information | enzyme has a strong preference for the Fe2+ cofactor under anaerobic conditions, regardless of the metal ion content of the medium. The preferred cofactor changes between Zn2+ and Fe2+ depending on the metal ion content of the medium when MshB is purified under aerobic conditions | Mycolicibacterium smegmatis | |
Ni2+ | activity follows the trend Fe2+>Co2+>Zn2+>Mn2+ and Ni2+ | Mycolicibacterium smegmatis | |
