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 is found at the N-terminal of TiaS and it is responsible for ATP binding [1,2].	Domain
A, B, C, D	PF08489	TiaS FLD domain (TiaS_FLD)	TiaS FLD domain	This is the FLD domain found in tRNA(Ile2) 2-agmatinylcytidine synthetase TiaS. TiaS is an archaeal ATP-dependent agmatine transferase that catalyses the formation of 2-agmatinylcytidine (agm2C) at the wobble position (C34) of tRNA(Ile2) [1-3]. This ...	This is the FLD domain found in tRNA(Ile2) 2-agmatinylcytidine synthetase TiaS. TiaS is an archaeal ATP-dependent agmatine transferase that catalyses the formation of 2-agmatinylcytidine (agm2C) at the wobble position (C34) of tRNA(Ile2) [1-3]. This modified base specifically recognises AUA codons. TiaS consists of four domains, the TCKD domain (Pfam:PF22641) at the N-terminal followed by the FLD domain, an OB fold domain and a zinc ribbon domain (ZRD) domain at the C-terminal [2]. This domain is responsible for agmantine binding [1].	Domain
