N-terminal domain of tRNA(Ile)-lysidine synthase and similar proteins; tRNA(Ile)-lysidine synthase (EC 6.3.4.19), also called tRNA(Ile)-2-lysyl-cytidine synthase or tRNA(Ile)-lysidine synthetase, catalyzes the ligation of lysine onto the cytidine present at position 34 of the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an ATP-dependent manner. Cytidine is converted to lysidine, thus changing the amino acid specificity of the tRNA from methionine to isoleucine. This subfamily belongs to the adenine nucleotide alpha hydrolase superfamily that also includes N-type ATP PPases and ATP sulfurylases. It forms an alpha/beta/alpha fold which binds to adenosine group. This domain has a strongly conserved motif SGGXD at the N-terminus.

tRNA(Ile)-lysidine synthetase, N-terminal domain; The only examples in which the wobble position of a tRNA must discriminate between G and A of mRNA are AUA (Ile) vs. AUG (Met) and UGA (stop) vs. UGG (Trp). In all bacteria, the wobble position of the tRNA(Ile) recognizing AUA is lysidine, a lysine derivative of cytidine. This family describes a protein domain found, apparently, in all bacteria in a single copy. Eukaryotic sequences appear to be organellar. The domain archictecture of this protein family is variable; some, including characterized proteins of E. coli and B. subtilis known to be tRNA(Ile)-lysidine synthetase, include a conserved 50-residue domain that many other members lack. This protein belongs to the ATP-binding PP-loop family ( pfam01171). It appears in the literature and protein databases as TilS, YacA, and putative cell cycle protein MesJ (a misnomer).

TtuA belongs to the adenine nucleotide alpha hydrolase superfamily (AANH) that includes N-type ATP PPases and ATP sulfurylases. It forms an alpha/beta/alpha fold which binds to the adenosine group.

cytoplasmic tRNA 2-thiolation protein 1 and similar proteins; This subfamily includes human cytoplasmic tRNA 2-thiolation protein 1, also called cytosolic thiouridylase subunit 1 (CTU1), ATP-binding domain-containing protein 3 (ATPBD3), cancer-associated gene protein, or cytoplasmic tRNA adenylyltransferase 1. CTU1 plays a central role in 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of tRNA(Lys), tRNA(Glu) and tRNA(Gln). It directly binds tRNAs and probably acts by catalyzing adenylation of tRNAs, an intermediate required for 2-thiolation. The CTU1-like subfamily belongs to the nucleotide alpha hydrolase (AANH) superfamily that includes N-type ATP PPases and ATP sulfurylases. It forms an alpha/beta/alpha fold which binds to the adenosine group.

7-cyano-7-deazaguanine synthase QueC and similar proteins; 7-cyano-7-deazaguanine synthase (EC 6.3.4.20) is also called 7-cyano-7-carbaguanine synthase, preQ(0) synthase, or queuosine biosynthesis protein QueC. It catalyzes the ATP-dependent conversion of 7-carboxy-7-deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)), as part of the biosynthesis pathway of queuosine (Q). Q is one of the most complex modifications occurring at the wobble position of tRNAs with GUN anticodons, and is implicated in a number of biological activities, including accuracy of decoding, virulence, and cellular differentiation. This subfamily belongs to the adenine nucleotide alpha hydrolase (AANH) superfamily that also includes other N-type ATP PPases and ATP sulfurylases. It forms an alpha/beta/alpha fold which binds to the adenosine group.
