STRING protein interaction network
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

thiIThiazole biosynthesis/tRNA modification protein ThiI; 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. (408 aa)    
Predicted Functional Partners:
iscS
Cysteine desulfurase NifS; 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 atoms 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.

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.

AGB03674.1
MiaB-like tRNA modifying enzyme; PFAM: Radical SAM superfamily; Uncharacterized protein family UPF0004; TIGRFAM: MiaB-like tRNA modifying enzyme, archaeal-type; radical SAM methylthiotransferase, MiaB/RimO family.

Hypothetical protein.

valS
valyl-tRNA synthetase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 2 subfamily.

ABC-type cobalt transport system, permease component CbiQ; PFAM: Cobalt transport protein.
 
   
 0.464
sepS
O-phosphoseryl-tRNA(Cys) synthetase; Catalyzes the attachment of O-phosphoserine (Sep) to tRNA(Cys).
 
  
 0.463
truA
Pseudouridylate synthase I; Formation of pseudouridine at positions 38, 39 and 40 in the anticodon stem and loop of transfer RNAs; Belongs to the tRNA pseudouridine synthase TruA family.
