Role of the RNA polymerase trigger loop in nucleotidyl transfer, transcript cleavage, and transcriptional pausing

The trigger loop (TL) is a polymorphous component of RNA polymerase (RNAP) that makes direct substrate contacts and promotes nucleotide addition when folded into an α-helical hairpin (trigger helices; TH). However, the roles of the TL/TH in transcript cleavage, catalysis, substrate selectivity, and...
