Isolation and characterization of an acetylene-resistant nitrogenase.

The Journal of biological chemistry - 14 Apr 2000

Christiansen J, Cash V L, Seefeldt L C, Dean D R

Abstract excerpt

A genetic strategy was developed for the isolation of a mutant strain of Azotobacter vinelandii that exhibits in vivo nitrogenase activity resistant to inhibition by acetylene. Examination of the kinetic features of the altered nitrogenase MoFe protein produced by this strain, which has serine substituted for the alpha-subunit Gly(69) residue, is consistent with other studies that indicate the MoFe protein...
