Using the method of synthesizing the disulfide form of CoA in a system with dried cells of Brevibacterium ammoniagenes developed previously, we have obtained labeled CoA with a yield of 15% calculated on the initial of [3H]-pantothenate introduced into the reaction medium. The purity of the preparation obtained, after purification using ion-exchange chromatography was 95% in terms of radioactivity. A possible pathway for the production of labeled phosphopantothenate in a system with a cell-free extract of Br. ammoniagenes is considered. According to preliminary results, the phosphorylation of the pantothenate amounted to 30–40%. This system is unsuitable for obtaining labelled phosphopantetheine.
