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

PMM1574Conserved hypothetical protein; Alternative locus ID: PMED4_17841. (148 aa)    
Predicted Functional Partners:
ppc
Phosphoenolpyruvate carboxylase; Forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle.
  
  
 0.949
trpE
Anthranilate synthase component I and chorismate binding enzyme; Definite assignment; Alternative locus ID: PMED4_17871.
  
    0.707
PMM1576
Conserved hypothetical protein; Alternative locus ID: PMED4_17861.
       0.704
psaD
Photosystem I protein PsaD; Alternative locus ID: PMED4_17881.
  
    0.608
recF
Putative DNA repair and genetic recombination protein RecF; The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP; Belongs to the RecF family.
  
    0.534
rnhA
Possible ribonuclease HI; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids.
   
  
 0.504
ftsZ
Cell division protein FtsZ:Tubulin/FtsZ family; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.
   
  
 0.499
atpF
ATP synthase B/B' CF(0); F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation.
   
  
 0.495
guaA
Glutamine amidotransferase class-I:GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
  
 0.482
PMM1579
Conserved hypothetical protein; Alternative locus ID: PMED4_17891.
  
    0.480
