Ribosomal protein S1-like RNA-binding domain
SMART accession number:SM00316
Description: -
Interpro abstract (IPR022967):

The S1 domain was originally identified in ribosomal protein S1 but is found in a large number of RNA-associated proteins. The structure of the S1 RNA-binding domain from the Escherichia 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 [ (PUBMED:9008164) ].

The structure of the S1 domain is very similar to that of cold shock proteins. This suggests that they may both be derived from an ancient nucleic acid-binding protein [ (PUBMED:9008164) ].
