Domains within RbpA Serve Specific Functional Roles That Regulate the Expression of Distinct Mycobacterial Gene Subsets

Abstract excerpt

ABSTRACT The RNA polymerase (RNAP) binding protein A (RbpA) contributes to the formation of stable RNAP-promoter open complexes (RP o ) and is essential for viability in mycobacteria. Four domains have been identified in the RbpA protein, i.e., an N-terminal tail (NTT) that interacts with RNAP β′ and σ subunits, a core domain (CD) that contacts the RNAP β′ subunit, a basic linker (BL) that binds DNA, and a...
