Iron-molybdenum cofactor synthesis in Azotobacter vinelandii Nif- mutants.

J Imperial, V K Shah, R A Ugalde, P W Ludden, W J Brill.

Abstract

Nif- mutants of Azotobacter vinelandii defective in dinitrogenase activity synthesized iron-molybdenum cofactor (FeMo-co) and accumulated it in two protein-bound forms: inactive dinitrogenase and a possible intermediate involved in the FeMo-co biosynthetic pathway. FeMo-co from both these proteins could activate apo-dinitrogenase from FeMo-co-deficient mutants.
