Construction and functional analyses of a comprehensive sigma54 site-directed mutant library using alanine-cysteine mutagenesis.

abstract：:RNA molecules of > 20 nucleotides have been the focus of numerous recent NMR structural studies. Several investigators have used the UNCG family of hairpins to ensure proper folding. We show that th UUCG hairpin has a minimum requirement of a two base-pair stem. Hairpins with a CG loop closing base pair and an initial...
