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.

EV02_0010Ribonucleotide reductase of class II (coenzyme B12-dependent); Alternative locus ID: PSB_1407. (777 aa)    
Predicted Functional Partners:
EV02_0978
Deoxycytidine triphosphate deaminase; Alternative locus ID: PSB_0446.
     
 0.875
ribBA
3,4-dihydroxy-2-butanone 4-phosphate synthase; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
     
  0.872
EV02_0660
GTP cyclohydrolase I type 1; Alternative locus ID: PSB_0128.
     
  0.872
EV02_1032
GTP pyrophosphokinase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance.
     
  0.872
EV02_1068
Hypothetical protein; Alternative locus ID: PSB_0536; FIG00940962: hypothetical protein.
     
  0.872
ndk
Nucleoside diphosphate kinase; 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.
     
  0.872
pyrG
CTP synthase; 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.
     
  0.872
EV02_1792
Septum formation protein Maf; Nucleoside triphosphate pyrophosphatase. May have a dual role in cell division arrest and in preventing the incorporation of modified nucleotides into cellular nucleic acids.
     
  0.872
EV02_0241
Pyruvate kinase; Alternative locus ID: PSB_1638; Belongs to the pyruvate kinase family.
     
 0.791
EV02_0766
Hypothetical protein; Alternative locus ID: PSB_0234; FIG00940877: hypothetical protein.
