TranscriptomicsIdentification of promoter sequence elements involved in specific recognition by the ?S subunit of bacterial RNA polymerase.
Promoter recognition by bacterial RNA polymerase is mediated by ? subunits, which assemble transiently to RNA polymerase core enzyme (E) during transcription initiation. ? subunits drive transcription of specific sets of genes by allowing RNA polymerase to interact with different promoter sequences....

TranscriptomicsComparative genomics reveals new molecular targets for accelerated strain improvement of rifamycin B-producing strains
In the present study, we have used a genomic approach to understand how the classical mutate-and-screen method actually generated an improved rifamycin B producer. Compared with the reference strains Amycolatopsis mediterranei S699 (rifamycin B producer) and U32 (rifamycin SV producer), a total of 2...
