WebFeb 1, 2013 · The RNAP core enzyme was purified from T. thermophilus cells as described previously (Vassylyeva et al., 2002 ). For the in vitro reconstitution of the backtracked complexes, 25 µ M RNA, 25 µ M template DNA and 25 µ M nontemplate DNA were mixed with 20 µ M RNAP in 10 m M Tris–HCl buffer pH 7.7 containing 150 m M sodium chloride … WebThe genome of the extremely thermophilic T. thermophilus phage P23–45 does not possess RNAP coding sequences. The host RNAP cannot identify the conserved 11-bp motif in the early gene promoters. Nevertheless, host RNAP in combination with phage gp76 and gp39 proteins regulate the transcription of middle and late genes. WebNov 21, 2000 · This evidence suggests that T. thermophilus RNAP possesses less intrinsic binding energy than E. coli RNAP.
