Molecular diversity of the ribulose-1,5-diphosphate carboxylase from photosynthetic microorganisms

Abstract

The ribulose-1,5-diphosphate carboxylases from green and blue-green algae and the purple sulfur photosynthetic bacterium Chromatium are proteins with high molecular weights and with sedimentation coefficients of 18 to 21 Svedberg units. The carboxylases of the Athiorhodaceae are smaller, that of Rhodospirillum rubrum being a 6.2S molecule, and those of the two species of Rhodopseudomonas are 12S and 14.5S.
