Primary source abstract: "[Researchers] examined the kinetics of open complex formation at the lacP1 promoter using tryptophan fluorescence of RNA polymerase and DNA fragments with 2-aminopurine substituted at specific positions." |
Comments |
P.118 caption to fig.1c: "In particular, making the simplest assumption that the genomic background for RNAP is given only by the non-specific binding of RNAP with DNA, [investigators] take K[NS]pd=10 000 nM [ref 37], for the lac promoter K[S]pd=550 nM [primary source] and for the T7 promoter, K[S]pd=3nM [BNID 103592]. For the lac promoter, this results in Δɛpd=-2.9kBT and for the T7 promoter, Δɛpd=-8.1kBT." |
