Question

the metal ions present in the active site of nitrogenase enzyme co-factor are
1)Fe-M
2)Fe-W
3)Fe-Cu
4)Fe-Ni
​

Answer 1

Answer:

4) is the answer of your question

Answer 2

Option (4) - Fe-Ni

The metal ions present in the active site of the nitrogenase enzyme co-factor are Fe-Ni

Explanation:

• Nitrogenase enzymes are those which are produced by bacteria such as cyanobacteria and rhizobacteria.
• Cyanobacteria are also known as blue-green bacteria.

• These enzymes are involved in the reduction of Nitrogen and Ammonia.
• They are evolved as complex iron-sulfur-containing nitrogenase cofactors which mostly contain molybdenum or Nickel.
• Certain others contain vanadium but exist as Vanadium (VFe) and heterometal independent forms.
