1.2.7.4 | A110C |
alpha subunit mutant enzyme showing electron paramagnetic resonance spectrum after Ni-activation |
687824 |
1.2.7.4 | A110C |
mutation within tunnel region of alpha subunit, absence of strong cooperative inhibition of CO, no synthesis of acetyl-CoA |
655801 |
1.2.7.4 | A121H/H122A |
11% of wild type activity |
654754 |
1.2.7.4 | A219F |
mutant designed to block tunnel between Ni-Fe-S active site clusters, little enzymic activity. Metal clusters are properly assembled, impaired ability of CO to migrate through the tunnel |

1.2.7.4 | A222L |
alpha subunit mutant enzyme showing electron paramagnetic resonance spectrum after Ni-activation |
687824 |
1.2.7.4 | A222L |
mutation within tunnel region of alpha subunit, absence of strong cooperative inhibition of CO, no synthesis of acetyl-CoA |
655801 |
1.2.7.4 | A265M |
mutation within tunnel region of alpha subunit, absence of strong cooperative inhibition of CO, little synthesis of acetyl-CoA |
655801 |
1.2.7.4 | A578C |
mutant designed to block tunnel between Ni-Fe-S active site clusters, little enzymic activity. Metal clusters are properly assembled, impaired ability of CO to migrate through the tunnel |
674925 |
1.2.7.4 | C316S |
0.3% of wild type activity |
654754 |
1.2.7.4 | C338A |
complete loss of activity. Unable to grow in the dark with CO as the energy source, amount of enzyme present in membrane fraction is similar to wild-type as well as accumulation of Ni2+ |
