Molecular insights into nitrogenase FeMoco insertion--the role of His 274 and His 451 of MoFe protein alpha subunit.

Journal of inorganic biochemistry - 1 Nov 2007

Abstract excerpt

The final step of FeMo cofactor (FeMoco) assembly involves the insertion of FeMoco into its binding site in the molybdenum-iron (MoFe) protein of nitrogenase. Here we examine the role of His alpha274 and His alpha451 of Azotobacter vinelandii MoFe protein in this process. Our results from combined metal, activity, EPR, stability and insertion analyses show that mutations of His alpha274 and/or His alpha451, two...
