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

SERP0235Conserved hypothetical protein; May function as heme-dependent peroxidase. (249 aa)    
Predicted Functional Partners:
hemH
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX. Belongs to the ferrochelatase family.
 
 
 0.983
ctaB
Protoheme IX farnesyltransferase; Converts heme B (protoheme IX) to heme O by substitution of the vinyl group on carbon 2 of heme B porphyrin ring with a hydroxyethyl farnesyl side group; Belongs to the UbiA prenyltransferase family. Protoheme IX farnesyltransferase subfamily.
  
  
  0.927
isdG
Conserved hypothetical protein; Allows bacterial pathogens to use the host heme as an iron source. Catalyzes the oxidative degradation of the heme macrocyclic porphyrin ring to the oxo-bilirubin chromophore staphylobilin (a mixture of the linear tetrapyrroles 5-oxo-delta-bilirubin and 15-oxo- beta-bilirubin) in the presence of a suitable electron donor such as ascorbate or NADPH--cytochrome P450 reductase, with subsequent release of free iron.
  
  
 0.921
lipL
Lipoate-protein ligase A family protein; Catalyzes the amidotransfer (transamidation) of the octanoyl moiety from octanoyl-GcvH to the lipoyl domain of the E2 subunit of lipoate-dependent enzymes; Belongs to the octanoyltransferase LipL family.
 
   
 0.846
pta
Phosphate acetyltransferase; Identified by similarity to SP:P39646; match to protein family HMM PF01515; match to protein family HMM TIGR00651.
       0.815
hemG
Protoporphyrinogen oxidase; Catalyzes the 6-electron oxidation of protoporphyrinogen-IX to form protoporphyrin-IX.
 
  
 0.711
ctaA
Cytochrome oxidase assembly protein; Catalyzes the oxidation of the C8 methyl side group on heme O porphyrin ring into a formyl group; Belongs to the COX15/CtaA family. Type 1 subfamily.
 
    0.615
SERP0707
Conserved hypothetical protein; Identified by similarity to OMNI:SA1126; match to protein family HMM PF04238.
  
    0.531
pcrB
Geranylgeranylglyceryl phosphate synthase family protein; Prenyltransferase that catalyzes in vivo the transfer of the heptaprenyl moiety of heptaprenyl pyrophosphate (HepPP; 35 carbon atoms) to the C3 hydroxyl of sn-glycerol-1-phosphate (G1P), producing heptaprenylglyceryl phosphate (HepGP). This reaction is an ether-bond- formation step in the biosynthesis of archaea-type G1P-based membrane lipids found in Bacillales.
  
     0.502
SERP0916
Conserved hypothetical protein; Identified by similarity to OMNI:SA1380.
  
     0.487
