The intrinsically disordered AR2 domain of RNase E binds mRNA translation initiation regions
Intrinsically disordered regions are widespread in RNA-processing machines. In Escherichia coli, RNase E uses its intrinsically disordered C-terminal domain (CTD) to recruit RNAs to the N-terminal catalytic domain, including mRNAs targeted by regulatory small RNAs (sRNAs), but the basis of substrate recognition and specificity is unclear. We engineered a protease-cleavable RNase E and used…
