abstractText | Carbamyl phosphate synthetase-I (CPS-I)2, purified from mouse hepatic mitochondria consists of electrophoretically homogeneous polypeptide species of 160 kilodaltons molecular weight (Kd). Monospecific antibody to CPS-I immunoprecipitated a putative precursor of 165Kd protein from in vitro translation products programmed with mouse liver free polysomes or poly(A) RNA. Isolated mitochondrial particles can take up and process pCPS-I into mature CPS-I of 160Kd in an in vitro transport system. The in vitro transport of CPS-I is energy dependent and requires intact mitochondria. The processing of pCPS-I appears to involve a single endoproteolytic cleavage. |
