Abstract

The hupR1 gene from Rhodobacter capsulatus was cloned and sequenced. It can encode a protein of 53,843 Da which shares significant similarity with several transcriptional regulators and activates transcription of the structural hupSL genes of [NiFe]hydrogenase, as shown by the use of a translational fusion of lacZ with the hupSL promoter. A Hup- mutant having a point mutation in the hupR1 gene is described.
