Document Summary

Subunits of prokaryotic rnap, subunit ( ), chain initiation. Interacts with regulatory proteins and upstream promoter elements: (cid:533) subunit (1, chain initiation and elongation, (cid:533)" subunit (1, dna binding, subunit (1) Promoter recognition: subunit (1, unknown, sequence positions of e. coli promoter elements and interactions, -35 consensus sequence. 4 binds to the -35 region: -10 consensus sequence (pribnow box) Binds to the -10 region: rnap reaction substrates and products, substrates: Template dna ribonucleotides: products, rna strand (cid:533)-phosphate and (cid:534)-phosphate, eukaryotic rnap and functions, rnap i: multisubunit. Transcribes protein-encoding genes and a few small rna genes. Active in nucleoplasm: mtrna polymerase: single polypeptide (related to dna pol i) 16s and 23s species, and the locations of trna sequences embedded within the transcript are shown: trna is embedded within larger rna structures and are isolated after rrna gets processed, in yeast: " oh at branch point a attacks 5" splice site at ag | g: lariat forms with intron.
