The C. acetobutylicum ptb gene encodes phosphotransbutyrylase, a key enzyme in butyrate production that converts butyryl-CoA to butyryl-phosphate. Notably, this reaction is reversible, allowing ptb to participate not only in butyrate synthesis but also in its re-assimilation. Consistent with this dual functionality, strains carrying elevated copies of ptb (together with buk) show more extensive re-assimilation of butyric acid [353].
