Autophosphorylation and phosphatase activities of the oxygen-sensing protein FixL of Rhizobium meliloti are coordinately regulated by oxygen.

The Journal of biological chemistry - 25 Feb 1993

Abstract excerpt

The FixL and FixJ proteins of Rhizobium meliloti control the expression of other nif and fix genes in response to oxygen levels. FixL is a hemoprotein kinase that senses oxygen availability and responds to the absence of oxygen by activation of its autophosphorylating activity followed by transfe...
