Prominent polypeptides with apparent molecular masses of 180, 120, 85, and 38 kDa are found in an extensively purified preparation of maize chloroplast DNA-dependent RNA polymerase that retains the capacity to initiate transcription of the cloned chloroplast gene rbcL correctly and the requirement for a supercoiled DNA template for specific and active transcription. Amino-terminal amino acid sequences of the 180-, 120-, and 38-kDa polypeptides have been determined and found to correspond precise ...[more]
