RESUMO
The DNA-dependent RNA polymerase (EC 2.7.7.6) of the myxobacterium Stigmatella aurantiaca has been purified. It shows three main polypeptide bands with apparent molecular weights of 146,000, 105,000, and 40,000 in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. beta and beta' subunits of the S. aurantiaca polymerase were shown to migrate in the 146,000-molecular-weight polypeptide band and the main sigma factor was shown to migrate in the 105,000-molecular-weight band by using heterologous antisera.
