Abstract: | Summary Studies were conducted of the oxidative metabolism of propionate in Rhodospirillum rubrum, using C14-labeled compounds. The results, taken in conjunction with a carbon dioxide requirement described previously (Clayton et al., 1957), reveal that the first step is a carboxylation of propionic acid, yielding succinic acid. This result is confirmed through manometric studies of inhibition by malonate. |
