This family contains OB-fold domains that bind to nucleic acids [4]. The family includes the anti-codon binding domain of lysyl, aspartyl, and asparaginyl -tRNA synthetases (See Pfam:PF00152). Aminoacyl-tRNA synthetases catalyse the addition of an amino acid to the appropriate tRNA molecule EC:6.1.1.-. This family also includes part of RecG helicase involved in DNA repair. Replication factor A is a hetero-trimeric complex, that contains a subunit in this family [2,3]. This domain is also found at the C-terminus of bacterial DNA polymerase III alpha chain.	Domain

STN1 is a component of the CST complex, a complex that binds to single-stranded DNA and is required for protecting telomeres from DNA degradation. The CST complex binds single-stranded DNA with high affinity in a sequence-independent manner, while isolated subunits bind DNA with low affinity on their own. In addition to telomere protection, the CST complex probably has a more general role in DNA metabolism at non-telomeric sites. This entry represents the C-terminal region of Stn1 which has two winged helix-turn-helix (wHTH) motifs, wHTH1 and wHTH2 [2,4]. wHTH1 is structurally similar to that in RPA32 with a large insertion between helices alpha2 and alpha3, unique to Stn1, that may allow interaction with a different set of proteins that function at telomeres such as Ctc1 [4]. wHTH2 is most similar to the DNA-binding wHTH motifs of the pur operon repressor and RepE replication initiator, but it does not bind double-stranded DNA [5].
