This family is expressed by almost all bacterial and eukaryotic genomes but not by archaea. Its function is to down-regulate protein synthesis under conditions of nutrient shortage, and it does this by binding to protein L14 of the large ribosomal subunit, thus acting as a ribosomal silencing factor (RsfS) by blocking the joining of the ribosomal subunits [1]. This family is structurally homologous to nucleotidyltransferases.	Domain
