| Popis: | Cell-free extracts of methane-utilizing bacteria (methylobacteria) were examined for the presence of enzymes of the tricarboxylic acid cycle. Representative organisms of the Type II group had a complete set of enzymes for the operation of this cycle. Members of the Type I group lacked α-ketoglutarate dehydrogenase. All the methylobacteria examined had an NADH-oxidase which had the properties of a flavoprotein type enzyme. Glucose-6-phosphate dehydrogenase and gluconate-6-phosphate dehydrogenase was NADP-specific and could only be detected in cell extracts of Type I methylobacteria. |
