Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
iscSCysteine desulfurase (tRNA sulfurtransferase), PLP-dependent; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins. Preferentially binds to disordered IscU on which the Fe-S is assembled, IscU converts to the structured state and then dissociates from IscS to transfer the Fe-S to a [...] (404 aa)
tusDSulfurtransferase for 2-thiolation step of mnm(5)-s(2)U34-tRNA synthesis; Part of a sulfur-relay system required for 2-thiolation of 5- methylaminomethyl-2-thiouridine (mnm(5)s(2)U) at tRNA wobble positions. Accepts sulfur from TusA and transfers it in turn to TusE. (128 aa)
tusAmnm(5)-s(2)U34-tRNA 2-thiolation sulfurtransferase; Sulfur carrier protein involved in sulfur trafficking in the cell. Part of a sulfur-relay system required for 2-thiolation during synthesis of 2-thiouridine of the modified wobble base 5- methylaminomethyl-2-thiouridine (mnm(5)s(2)U) in tRNA. Interacts with IscS and stimulates its cysteine desulfurase activity. Accepts an activated sulfur from IscS, which is then transferred to TusD, and thus determines the direction of sulfur flow from IscS to 2-thiouridine formation. Also appears to be involved in sulfur transfer for the biosynthesi [...] (81 aa)
mnmEtRNA U34 5-methylaminomethyl-2-thiouridine modification GTPase; Exhibits a very high intrinsic GTPase hydrolysis rate. Involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA- cmnm(5)s(2)U34. (454 aa)
mnmG5-methylaminomethyl-2-thiouridine modification at tRNA U34; NAD-binding protein involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA-cmnm(5)s(2)U34. (629 aa)
phoAAlkaline phosphatase; start codon corrected; Protein involved in phosphorus metabolic process; Belongs to the alkaline phosphatase family. (471 aa)
tilStRNA(Ile)-lysidine synthetase; Ligates 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 enzyme is essential for viability. (432 aa)
thiItRNA s(4)U8 sulfurtransferase; Catalyzes the ATP-dependent transfer of a sulfur to tRNA to produce 4-thiouridine in position 8 of tRNAs, which functions as a near-UV photosensor. Also catalyzes the transfer of sulfur to the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a step in the synthesis of thiazole, in the thiamine biosynthesis pathway. The sulfur is donated as persulfide by IscS. Belongs to the ThiI family. (482 aa)
glnSGlutamine tRNA synthetase; Protein involved in tRNA aminoacylation for protein translation. (554 aa)
moaDMolybdopterin synthase, small subunit; Involved in sulfur transfer in the conversion of molybdopterin precursor Z to molybdopterin. Belongs to the MoaD family. (81 aa)
tusEmnm(5)-s(2)U34-tRNA 2-thiolation sulfurtransferase; Part of a sulfur-relay system required for 2-thiolation of 5- methylaminomethyl-2-thiouridine (mnm(5)s(2)U) at tRNA wobble positions. Could accept sulfur from TusD. (109 aa)
moeBMolybdopterin synthase sulfurylase; Catalyzes the adenylation by ATP of the carboxyl group of the C-terminal glycine of sulfur carrier protein MoaD. (249 aa)
mnmAtRNA(Gln,Lys,Glu) U34 2-thiouridylase; Catalyzes the 2-thiolation of uridine at the wobble position (U34) of tRNA(Lys), tRNA(Glu) and tRNA(Gln), leading to the formation of s(2)U34, the first step of tRNA-mnm(5)s(2)U34 synthesis. Sulfur is provided by IscS, via a sulfur-relay system. Binds ATP and its substrate tRNAs. (368 aa)
ttcAtRNA s(2)C32 thioltransferase, iron sulfur cluster protein; Catalyzes the ATP-dependent 2-thiolation of cytidine in position 32 of tRNA, to form 2-thiocytidine (s(2)C32). The sulfur atoms are provided by the cysteine/cysteine desulfurase (IscS) system. Belongs to the TtcA family. (311 aa)
tmcAElongator methionine tRNA (ac4C34) acetyltransferase; Catalyzes the formation of N(4)-acetylcytidine (ac(4)C) at the wobble position of tRNA(Met), by using acetyl-CoA as an acetyl donor and ATP (or GTP). It recognizes the wobble base of tRNA(Met), thus distinguishing between tRNA(Met) and the structurally similar tRNA(Ile2). (671 aa)
