Abstract

The subunits of purified yeast RNA polymerases I, II and III have been analyzed by two-dimensional polyacrylamide gel electrophoretic subunit mapping techniques. The results suggest that polymerases I and III have two subunits in common, the 41,000 and 20,000 dalton peptides, which are not present in polymerase III. The 14,500 dalton peptide by all criteria is identical in polymerases I, II and III. The 28,000 and 24,000 subunits appear identical in polymerases I and II but have different charge properties in polymerase III.
