Genes coding for RNA-polymerase in bacteria. II. Conservative sites in the central region of the beta-subunit of Pseudomonas putida RNA-polymerase
SalI--L fragment of the P. putida rpoBC operon has been sequenced and conservative regions of the central part of the RNA-polymerase beta-subunit have been determined. Amino and acid residues interacting with Zn2+ are postulated.
