Role of Era in assembly and homeostasis of the ribosomal small subunit.

abstract：:Restriction fragments of T7 DNA which selectively bind E. coli RNA polymerase have been identified. These include fragments located close to the beginning of gene 1 where according to Minkley and Pribnow (1973) there is a promoter called C. The smallest fragment from this region which binds RNA polymerase has been seq...
