STRINGSTRING
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

MJ_0107Dihydropteroate synthase; Unknown. Does not possess dihydropteroate synthase (DHPS) activity since it does not catalyze the condensation of 6- hydroxymethyl-7,8-dihydropterin pyrophosphate (DHPP) and 4- aminobenzoate to form 7,8-dihydropteroate. (525 aa)    
Predicted Functional Partners:
mfnE
Delta 1-pyrroline-5-carboxylate synthetase; Catalyzes the formation of 5-(aminomethyl)-3-furanmethanol diphosphate (F1-PP) from 5-(aminomethyl)-3-furanmethanol phosphate (F1- P) and ATP. In vitro, can also act as an adenylate kinase that catalyzes the transfer of a phosphoryl group from ATP to AMP, generating two molecules of ADP.
 
   
 0.942
mfnB
Conserved hypothetical protein; Catalyzes the formation of 4-(hydroxymethyl)-2- furancarboxaldehyde phosphate (4-HFC-P) from two molecules of glyceraldehyde-3-P (GA-3-P).
 
   
 0.938
MJ_0108
Pyruvate kinase; Similar to GB:D13095 SP:Q02499 GB:X57859 PID:285623 percent identity: 38.82; identified by sequence similarity; putative.
     
 0.936
mfnF
Conserved hypothetical protein; Catalyzes the condensation between 5-(aminomethyl)-3- furanmethanol diphosphate (F1-PP) and gamma-glutamyltyramine to produce APMF-Glu.
 
   
 0.906
mfnD
Conserved hypothetical protein; Catalyzes the formation of an amide bond between tyramine and the gamma carboxy group of L-glutamate. The enzyme also accepts phenylethylamine in vitro.
  
   
 0.898
MJ_0301
Conserved hypothetical protein; Catalyzes the condensation of 6-hydroxymethyl-7,8- dihydropterin pyrophosphate (DHPP) with 4-(beta-D-ribofuranosyl)- aminobenzene-5'-phosphate (beta-RFA-P) to form 7,8-dihydropterin-6- methyl-4-(beta-D-ribofuranosyl)-aminobenzene-5'-phosphate, a precursor in the biosynthesis of 5,6,7,8-tetrahydromethanopterin (H4MPT). To a lesser extent, is able to condense beta-RFA-P with another arylamine, 1-(4-aminophenyl)-1-deoxy-D-ribitol (APDR), to form 7,8-dihydropterin- 6-methyl-1-(4-aminophenyl)-1-deoxy-D-ribitol. Dephosphorylated beta- RFA-P is not a substrate; [...]

MJ_1427
Hypothetical protein; Catalyzes the condensation of 4-aminobenzoate (pABA) with 5- phospho-alpha-D-ribose 1-diphosphate (PRPP) to produce beta- ribofuranosylaminobenzene 5'-phosphate (beta-RFA-P).

trpE
Anthranilate synthase component I (trpE); Part of a heterotetrameric complex that catalyzes the two- step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly from chorismate and high c [...]

ribH
Riboflavin synthase beta chain (ribH); Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2- butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin; Belongs to the DMRL synthase family.
  
  
 0.765
MJ_0226
Conserved hypothetical protein; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides xanthosine triphosphate (XTP), deoxyinosine triphosphate (dITP) and ITP. Probably functions as a house- cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Shows very low activity on GTP or dGTP, both of which are hydrolyzed more than 100-fold less efficiently than X [...]
