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.

tRNA-5-methyluridine(54) 2-sulfurtransferase and similar proteins; tRNA-5-methyluridine(54) 2-sulfurtransferase, also called tRNA thiouridine synthetase TtuA, catalyzes the ATP-dependent 2-thiolation of 5-methyluridine residue at position 54 in the T loop of tRNAs, leading to 5-methyl-2-thiouridine (m(5)s(2)U or s(2)T).

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.

C-terminal domain of GMP synthetase (glutamine-hydrolyzing); The C-terminal domain of GMP synthetase (glutamine-hydrolyzing, EC 6.3.5.2) contains two subdomains: the ATP pyrophosphatase domain at the N-terminal and the dimerization domain at the C-terminal end. The ATP-PPase domain is a twisted, five-stranded parallel beta-sheet sandwiched between helical layers. It has a signature nucleotide-binding motif, or PP-loop, at the end of the first-beta strand. GMP synthetase is a homodimer, but in some archaea, it is a heterodimer made up of ATP pyrophosphatase (ATP-PPase) and a GATase subunit. In eukaryotes and bacteria, the two catalytic units are encoded by a single gene producing a two-domain-type GMP with a GATase domain in the N-terminus and an ATP-PPase domain in the C-terminus.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.

Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
