This entry represents the OB fold of single-stranded DNA binding protein Ssb from archaea and its homologues from mammals and plants. Members of this entry have a simple domain organisation consisting of a single DNA-binding OB fold coupled to a flexible C-terminal tail [1-3]. The ssDNA recognition is modulated by base-stacking of three key aromatic residues in archaeal Ssb, in contrast with the OB domain of the human homologue hSSB1 [3].	Domain
