Localization of ribulose-bisphosphate carboxylase-oxygenase and its putative binding protein in the cell envelope ofChromatium vinosum

摘要

Antibodies to the large and small subunits of ribulose-bisphosphate carboxylase-oxygenase (RuBisCO; EC 4.1-1.39) and a putative binding protein (PBP) for RuBisCO fromChromatium vinosumhave been used to localize these proteins in thin sections. Immunogold techniques employing single and double antibodies establish that RuBisCO and the RuBisCO PBP are concentrated in the cell envelope ofC. vinosum.
