Some properties of DNA-dependent RNA polymerase from Streptomyces granaticolor.

RNA nucleotidyltransferase from Streptomyces granaticolor was purified and some of its properties were investigated. The temperature optimum of the enzyme is 35 degrees C, pH optimum 7.8-8.4. Antibodies against the beta subunit of the enzyme from Bacillus subtilis immunologically cross-react with the beta subunit of the enzyme from S. granaticolor. Antibodies against the beta' subunit of the enzyme from B. subtilis immunologically cross-react with both beta and beta' subunits of the enzyme from S. granaticolor.
