RESUMO
Cell extracts of Desulfovibrio vulgaris were found to incorporate 14CO2 into acid-stable products when ribose-5-phosphate or ribulose-1,5-diphosphate was used as a substrate. This CO2 fixation required adenosine triphosphate and produced 3-phosphoglyceric acid as one of the products. The assimilation of CO2 by pentose phosphates was unrelated to the pyruvate-CO2 exchange reaction. The pyruvate-CO2 exchange did not require adenosine triphosphate, did not produce phosphorylated compounds, and, unlike the pentose phosphate system, required an acidic protein fraction for activity.
