Amanitin-resistant RNA polymerase II mutations are in the enzyme's largest subunit.


Journal Article

A fragment of the Drosophila melanogaster RpIIC4 locus, which encodes the RNA polymerase II subunit that determines amanitin sensitivity, was inserted into a bacterial plasmid cloning vehicle useful for over-production of hybrid proteins. Two plasmid constructions encoded hybrid proteins that reacted with antibodies against D. melanogaster RNA polymerase II. Use of subunit-specific antibodies indicated that these hybrid proteins displayed antigenic determinants unique to the largest polypeptide (215 kDa) of the enzyme. This RpII locus, the site at which mutations to amanitin-resistance occur, must therefore encode the largest polymerase II subunit.
