FeMo cofactor synthesis by a nifH mutant with altered MgATP reactivity.

The Journal of biological chemistry - 15 Oct 1992

Gavini N, Burgess B K

Abstract excerpt

We have characterized a Nif- mutant of Azotobacter vinelandii, designated UW91 (Shah, V. K., Davis, L. C., Gordon, J. K., Orme-Johnson, W. H., and Brill, W. J. (1973) Biochim. Biophys. Acta 292, 246-255). The specific Fe protein mutation giving rise to the Nif- phenotype was shown by DNA sequencing and site-directed mutagenesis to be the substitution of a conserved alanine at position 157 by a serine. The UW91 Fe...
