A [auth Z]	PF22641	TiaS TCKD domain (TiaS_TCKD)	TiaS FLD domain	This domain is found in tRNA(Ile2) 2-agmatinylcytidine synthetase TiaS and related proteins. TiaS is an ATP-dependent agmatine transferase that catalyses the formation of 2-agmatinylcytidine (agm2C) at the wobble position (C34) of tRNA(Ile2) [1]. Thi ...	This domain is found in tRNA(Ile2) 2-agmatinylcytidine synthetase TiaS and related proteins. TiaS is an ATP-dependent agmatine transferase that catalyses the formation of 2-agmatinylcytidine (agm2C) at the wobble position (C34) of tRNA(Ile2) [1]. This domain binds agmatine.	Domain

A [auth Z]	PF01336	OB-fold nucleic acid binding domain (tRNA_anti-codon)	OB-fold nucleic acid binding domain	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 a ...	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
