Identification of a second site compensatory mutation in the Fe-protein that allows diazotrophic growth of Azotobacter vinelandii UW97.

FEBS letters - 28 Jul 2000

Lei S, Pulakat L, Suh M, Gavini N

Abstract excerpt

Azotobacter vinelandii UW97 is defective in nitrogen fixation due to a replacement of serine at position 44 by phenylalanine in the Fe-protein [Pulakat, L., Hausman, B.S., Lei, S. and Gavini, N. (1996) J. Biol. Chem. 271, 1884-1889]. Serine residue 44 is located in a conserved domain that links the nucleotide binding site and the MoFe-protein docking surface of the Fe-protein. Therefore, it is possible that the...
