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

hybDMaturation protease for hydrogenase 2; Protease involved in the C-terminal processing of HybC, the large subunit of hydrogenase 2. Specifically cleaves off a 15 amino acid peptide from the C-terminus of the precursor of HybC; Belongs to the peptidase A31 family. (164 aa)    
Predicted Functional Partners:
hybC
Hydrogenase 2, large subunit; This is one of three E.coli hydrogenases synthesized in response to different physiological conditions. HYD2 is involved in hydrogen uptake; Belongs to the [NiFe]/[NiFeSe] hydrogenase large subunit family.
 
  
 0.996
hybG
Hydrogenase 2 accessory protein; Involved in the maturation of [NiFe] hydrogenases. Involved in the biosynthesis of the Fe(CN)(2)CO cofactor. HybG delivers iron-bound CO(2) to HypD where reduction to CO probably occurs. In complex with HypD, accepts the cyanide ligand generated by HypF and HypE, and also coordinates the carbon monoxide ligand (By similarity). Involved in the maturation of the hydrogenase 2. Also participates in the maturation of hydrogenase 1.
 
  
 0.991
hybE
Hydrogenase 2-specific chaperone; Member of hyb operon.
 
  
 0.986
hybB
Putative hydrogenase 2 cytochrome b type component; Probable b-type cytochrome; Belongs to the NrfD family.
 
  
 0.983
hybO
Hydrogenase 2, small subunit; This is one of three E.coli hydrogenases synthesized in response to different physiological conditions. HYD2 is involved in hydrogen uptake; Belongs to the [NiFe]/[NiFeSe] hydrogenase small subunit family.
 
  
 0.983
hybF
Protein involved with the maturation of hydrogenases 1 and 2; Involved in the maturation of [NiFe] hydrogenases. Required for nickel insertion into the metal center of the hydrogenase. HybF is involved in maturation of hydrogenases 1 and 2. It may partially substitute for the function of HypA and vice versa.
 
  
 0.966
hyaB
Hydrogenase 1, large subunit; This is one of three E.coli hydrogenases synthesized in response to different physiological conditions. HYD1 is believed to have a role in hydrogen cycling during fermentative growth; Belongs to the [NiFe]/[NiFeSe] hydrogenase large subunit family.
 
  
 0.963
hybA
Hydrogenase 2 4Fe-4S ferredoxin-type component; Participates in the periplasmic electron-transferring activity of hydrogenase 2 during its catalytic turnover.
 
  
 0.947
hypF
Carbamoyl phosphate phosphatase and [NiFe] hydrogenase maturation protein; Involved in the maturation of [NiFe] hydrogenases. Along with HypE, it catalyzes the synthesis of the CN ligands of the active site iron of [NiFe]-hydrogenases. HypF functions as a carbamoyl transferase using carbamoylphosphate as a substrate and transferring the carboxamido moiety in an ATP-dependent reaction to the thiolate of the C-terminal cysteine of HypE yielding a protein-S-carboxamide. In the absence of any other substrate, displays carbamoyl-phosphate phosphatase activity.
 
  
 0.883
hyaC
Hydrogenase 1, b-type cytochrome subunit; Probable b-type cytochrome; Belongs to the HupC/HyaC/HydC family.
  
 0.873
