Introduction

Pfam

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 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.

InterPro

The OB-fold (oligonucleotide/oligosaccharide-binding fold) is found in all three kingdoms and its common architecture presents a binding face that has adapted to bind different ligands. The OB-fold is a five/six-stranded closed beta-barrel formed by 70-80 amino acid residues. The strands are connected by loops of varying length which form the functional appendages of the protein. The majority of OB-fold proteins use the same face for ligand binding or as an active site. Different OB-fold proteins use this 'fold-related binding face' to, variously, bind oligosaccharides, oligonucleotides, proteins, metal ions and catalytic substrates.
