RNA polymerase II elongation complex in 150 mm MG+2 with UTP
Overview
New structures of RNA polymerase II (pol II) transcribing complexes reveal a likely key to transcription. The trigger loop swings beneath a correct nucleoside triphosphate (NTP) in the nucleotide addition site, closing off the active center and forming an extensive network of interactions with the NTP base, sugar, phosphates, and additional pol II residues. A histidine side chain in the trigger loop, precisely positioned by these interactions, may literally "trigger" phosphodiester bond formation. Recognition and catalysis are thus coupled, ensuring the fidelity of transcription.
About this Structure
2YU9 is a Protein complex structure of sequences from Saccharomyces cerevisiae. This structure supersedes the now removed PDB entry 2nvs. Full crystallographic information is available from OCA.
