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

comAConserved hypothetical protein; Catalyzes the addition of sulfite to phosphoenolpyruvate (PEP) to yield (2R)-phospho-3-sulfolactate (PSL). (251 aa)    
Predicted Functional Partners:
MJ_0119
Carbon monoxide dehydrogenase gamma subunit (cdhE) isolog; Similar to PID:1002692 SP:Q50539 percent identity: 42.86; identified by sequence similarity; putative.
 
    0.999
MJ_0120
Urease accessory protein (ureG); Similar to GB:L24101 SP:P42871 PID:431755 percent identity: 34.53; identified by sequence similarity; putative.
  
    0.999
MJ_0121
SN-glycerol-3-phosphate transport ATP-binding protein (ugpC); Similar to SP:P10907 GB:U00039 PID:43249 PID:912455 GB:U00096 percent identity: 32.54; identified by sequence similarity; putative; Belongs to the ABC transporter superfamily.
  
    0.999
comB
Conserved hypothetical protein; Hydrolyzes both enantiomers of 2-phosphosulfolactate. Able to hydrolyze both enantiomers of 2-hydroxycarboxylic acids with pseudosymmetric centers of inversion. Specifically hydrolyzes (S)- phospholactate and (S)-phosphoglycerate.
 
 
 0.998
comC
Malate dehydrogenase; Catalyzes the reduction of sulfopyruvate to (R)-sulfolactate much more efficiently than the reverse reaction. Also catalyzes the reduction of oxaloacetate, alpha-ketoglutarate, and to a much lower extent, KHTCA, but not pyruvate. Involved in the biosynthesis of both coenzyme M (with (R)-sulfolactate) and methanopterin (with alpha- ketoglutarate).
     
 0.895
MJ_0664
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ0664.
  
    0.801
hypB
Hydrogenase expression/formation protein (hypB); Involved in the maturation of [NiFe] hydrogenases. Required for nickel insertion into the metal center of the hydrogenase. Exhibits a low intrinsic GTPase activity, which is essential for nickel insertion; Belongs to the SIMIBI class G3E GTPase family. HypB/HupM subfamily.
  
    0.749
pgk2
2-phosphoglycerate kinase (2pgk); Similar to GB:X70785 PID:467751 percent identity: 47.02; identified by sequence similarity; putative.
      
 0.663
mdh
L-lactate dehydrogenase EGAD|7256|705; Catalyzes the reversible oxidation of (S)-malate and (S)- sulfolactate to oxaloacetate and sulfopyruvate, respectively. Can use both NADH and NADPH, although activity is higher with NADPH. Oxidation of (S)-sulfolactate is observed only in the presence of NADP(+). Can also oxidize tartrate. Cannot reduce pyruvate, nor alpha-ketoglutarate. Belongs to the LDH/MDH superfamily.
      
 0.640
MJ_1623
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ1623.
   
    0.578
