  • The thiol redox balance in the periplasm of E. coli depends on the DsbA/B pair for oxidative 14 power and the DsbC/D system as its complement for isomerization of non-native disulfides. 15 While the standard redox potentials of those systems are known, the in vivo redox potential 16 imposed onto protein thiol disulfide pairs in the periplasm remains unknown. Here, we used 17 genetically encoded redox probes (roGFP2 ...

  • Pausing by RNA polymerase (RNAP) during transcription elongation, in which a translocating RNAP uses a “stepping” mechanism, has been studied extensively, but pausing by RNAP during initial transcription, in which a promoter-anchored RNAP uses a “scrunching” mechanism, has not. We report a method that directly defines RNAP-active-center position relative to DNA in vivo with single-nucleotide resolution (XACT-seq; crosslink-between-active-center-and-template sequencing). We apply this...
