Characterization of genes involved in molybdenum transport in Azotobacter vinelandii.

Molecular microbiology - 1 Feb 1993

Luque F, Mitchenall L A, Chapman M, Christine R, Pau R N

Abstract excerpt

Expression of alternative nitrogenases in Azotobacter vinelandii is repressed by molybdenum. Two strains with Tn5 insertion mutations showed alternative nitrogenase-dependent diazotrophic growth in the presence of Mo. The mutations were in a region which contained four open reading frames (ORFs 1-4). The genetic structure and predicted products of ORFs 2, 3 and 4 are typical of the membrane-associated elements of...
