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.

thiIThiamine biosynthesis protein; 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. (485 aa)    
Predicted Functional Partners:
PSHAa1138
Putative enzyme of the cysteine desulfurase family, metallo-beta-lactamase superfamily; Function proposed based on presence of conserved amino acid motif, structural feature or limited homolgy; enzyme.
  
 0.994
iscS
Cysteine desulfurase (tRNA sulfurtransferase; 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; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.
  
 0.972
iscS-2
Cysteine desulfurase (ThiI) (transpersulfidase) (NifS protein homolog); Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
 0.972
thiG
Thiazole biosynthesis protein; Catalyzes the rearrangement of 1-deoxy-D-xylulose 5-phosphate (DXP) to produce the thiazole phosphate moiety of thiamine. Sulfur is provided by the thiocarboxylate moiety of the carrier protein ThiS. In vitro, sulfur can be provided by H(2)S.

guaA
GMP synthetase (glutamine aminotransferase); Catalyzes the synthesis of GMP from XMP.
  
  
 0.693
thiDE
Putative phosphomethylpyrimidine kinase/thiamin-phosphate pyrophosphorylase; Condenses 4-methyl-5-(beta-hydroxyethyl)thiazole monophosphate (THZ-P) and 2-methyl-4-amino-5-hydroxymethyl pyrimidine pyrophosphate (HMP-PP) to form thiamine monophosphate (TMP). Belongs to the thiamine-phosphate synthase family.
 
   
 0.690
miaB
Involved in methylthiolation of isopentenylated A37 derivatives in tRNA, Fe-S protein; Catalyzes the methylthiolation of N6-(dimethylallyl)adenosine (i(6)A), leading to the formation of 2-methylthio-N6- (dimethylallyl)adenosine (ms(2)i(6)A) at position 37 in tRNAs that read codons beginning with uridine.
  
  
 0.659
pheT
Phenylalanine tRNA synthetase, beta-subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
