title: Cloning and sequence of the structural (hupSLC) and accessory (hupDHI) genes for hydrogenase biosynthesis in Thiocapsa roseopersicina.
abstract: The first molecular biology study on the purple sulfur photosynthetic bacterium Thiocapsa roseopersicina is reported, namely, the construction of cosmid libraries and isolation of a hydrogenase gene cluster by hybridization with hydrogenase structural genes from the purple non-sulfur bacterium, Rhodobacter capsulatus. The sequenced gene cluster contains six open reading frames, the products of which show significant degrees of identity (from 40 to 78%) with hydrogenase gene products necessary for biosynthesis of the group-I of [NiFe]hydrogenases. The structural hupSLC genes encode the small and large hydrogenase subunits and a hydrophobic protein shown to accept electrons from hydrogenase in R. capsulatus. They are followed downstream by three genes, hupDHI, which are similar to hydrogenase accessory genes found in other bacteria.
