RNA POLYMERASE II STRAND SEPARATED ELONGATION COMPLEX
Overview
The structure of an RNA polymerase II-transcribing complex has been determined in the posttranslocation state, with a vacancy at the growing end of the RNA-DNA hybrid helix. At the opposite end of the hybrid helix, the RNA separates from the template DNA. This separation of nucleic acid strands is brought about by interaction with a set of proteins loops in a strand/loop network. Formation of the network must occur in the transition from abortive initiation to promoter escape.
About this Structure
1SFO is a Protein complex structure of sequences from Saccharomyces cerevisiae with and as ligands. This structure supersedes the now removed PDB entry 1R9R. Active as DNA-directed RNA polymerase, with EC number 2.7.7.6 Full crystallographic information is available from OCA.
