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
C, F [auth Z]	PF08646	Replication factor-A C terminal domain (Rep_fac-A_C)	Replication factor-A C terminal domain	This domain is found at the C terminal of replication factor A. Replication factor A (RPA) binds single-stranded DNA and is involved in replication, repair, and recombination of DNA [1].	Domain
C, F [auth Z]	PF16900	Replication protein A OB domain (REPA_OB_2)	Replication protein A OB domain	Replication protein A contains two OB domains in it's DNA binding region. This is the second of the OB domains [1].	Domain
