nitrogen fixing bacteria
2
Q
What two proteins are involved in Nitrogenase?
A
Fe and MoFe
3
Q
What is the overall reaction of Nitrogenase?
A
N2 + 8H + 8e –> 2NH3 + H2
4
Q
What does the Fe protein do?
A
passes e from ferredoxin to the MoFe
5
Q
What is the Fe protein structure?
A
homodimer, one [4Fe4S] cluster
6
Q
What does the MoFe protein do?
A
binds and activates N2
7
Q
What is special about the MoFe protein?
A
can have multiple structures allows for variable positions, decrease in E and increase of et rate
