Protein
Hydrogenase transcriptional regulatory protein hupR1
Organism
Rhodobacter capsulatus
Function
Probable member of the two-component regulatory system involved in the regulation of the [NiFe] hydrogenase activity. HupR1 is probably phosphorylated by the sensory component and then acts in conjunction with sigma-54 as a transcriptional activator.
