S1 RNA BINDING DOMAIN, NMR, 20 STRUCTURES
Overview
The S1 domain, originally identified in ribosomal protein S1, is found in, a large number of RNA-associated proteins. The structure of the S1, RNA-binding domain from the E. coli polynucleotide phosphorylase has been, determined using NMR methods and consists of a five-stranded antiparallel, beta barrel. Conserved residues on one face of the barrel and adjacent, loops form the putative RNA-binding site. The structure of the S1 domain, is very similar to that of cold shock protein, suggesting that they are, both derived from an ancient nucleic acid-binding protein. Enhanced, sequence searches reveal hitherto unidentified S1 domains in RNase E, RNase II, NusA, EMB-5, and other proteins.
