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_0832Anaerobic ribonucleoside-triphosphate reductase (nrdD); Similar to SP:P28903 GB:L06097 GB:U06195 GB:Z46865 PID:146970 percent identity: 28.17; identified by sequence similarity; putative. (1750 aa)    
Predicted Functional Partners:
queE
Coenzyme PQQ synthesis protein III isolog (Haemophilus influenzae}; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.

MJ_1227
Pyruvate formate-lyase activating enzyme (act); Similar to GB:L42023 SP:P43751 PID:1003258 PID:1222095 PID:1204435 percent identity: 35.58; identified by sequence similarity; putative.
 
  
 0.947
ndk
Nucleoside diphosphate kinase, (ndk); Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
    
 0.921
pyrG
CTP synthase (pyrG); Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
    
 0.916
MJ_1559
Conserved hypothetical protein; Has nucleotide phosphatase activity towards ATP, GTP, CTP, TTP and UTP. May hydrolyze nucleoside diphosphates with lower efficiency (By similarity); Belongs to the THEP1 NTPase family.
   
 
 0.913
dcd
Deoxycytidine triphosphate deaminase (dcd); Bifunctional enzyme that catalyzes both the deamination of dCTP to dUTP and the hydrolysis of dUTP to dUMP without releasing the toxic dUTP intermediate. It also acts as a dUTP diphosphatase with a lower affinity for dUTP than for dCTP.
    
 0.911
dut
Deoxycytidine triphosphate deaminase, putative (dcd); This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA.
    
 0.911
MJ_0108
Pyruvate kinase; Similar to GB:D13095 SP:Q02499 GB:X57859 PID:285623 percent identity: 38.82; identified by sequence similarity; putative.
    
 0.905
MJ_0240
Conserved hypothetical protein; Could catalyze the biosynthesis of cyclic AMP (cAMP) from ATP.
     
  0.900
fen
DNA repair protein RAD2 (rad2); Structure-specific nuclease with 5'-flap endonuclease and 5'- 3' exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Binds the unpaired 3'-DNA end and kinks the DNA to facilitate 5' cleavage specificity. Cleaves one nucleotide into the double-stranded DNA from the junction in flap DNA, leaving a nick for ligation. Also involved in the base excision repair (BER) [...]
