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

hemBDelta-aminolevulinic acid dehydratase (hemB); Catalyzes an early step in the biosynthesis of tetrapyrroles. Binds two molecules of 5-aminolevulinate per subunit, each at a distinct site, and catalyzes their condensation to form porphobilinogen (By similarity). (323 aa)    
Predicted Functional Partners:
hemC
Porphobilinogen deaminase (hemC); Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps. Belongs to the HMBS family.
 
 0.999
hemL
Glutamate-1-semialdehyde 2,1-aminomutase (hemL); Similar to GB:D26562 SP:P23893 GB:X53696 PID:41621 PID:473813 percent identity: 51.30; identified by sequence similarity; putative.
 
 
 0.998
HP_1224
Uroporphyrinogen III cosynthase (hemD); Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
  
 0.929
hemA
glutamyl-tRNA reductase (hemA); Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA).
 
  
 0.900
HP_0162
Conserved hypothetical protein; Similar to PID:1183839 percent identity: 36.65; identified by sequence similarity; putative.
  
  
 0.879
arsR
Response regulator (ompR); Member of the two-component regulatory system ArsS/ArsR that regulates genes involved in biofilm formation and acid adaptation by acting on major ammonia-producing pathways. Upon phosphorylation by ArsS, functions as a transcription regulator by direct binding to promoter regions of target genes including ureA, amiE and amiF to positively regulate their expression in response to acidic pH. Negatively autoregulates its expression.
     
 0.740
atpD
ATP synthase F1, subunit beta (atpD); Produces ATP from ADP in the presence of a proton gradient across the membrane. The catalytic sites are hosted primarily by the beta subunits; Belongs to the ATPase alpha/beta chains family.
 
    
 0.723
arsS
Signal-transducing protein, histidine kinase; Member of the two-component regulatory system ArsS/ArsR that regulates genes involved in biofilm formation and acid adaptation by acting on major ammonia-producing pathways. Functions as a sensor protein kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to the conserved aspartic acid residue in the regulatory domain of ArsR. In turn, ArsR binds to the upstream promoter regions of target genes including ureA, amiE and amiF to positively regulate their expression in response to acidic pH. Participates [...]
     
 0.713
hemE
Uroporphyrinogen decarboxylase (hemE); Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.
 
 
 0.649
HP_0598
8-amino-7-oxononanoate synthase (bioF); Catalyzes the decarboxylative condensation of pimeloyl-[acyl- carrier protein] and L-alanine to produce 8-amino-7-oxononanoate (AON), [acyl-carrier protein], and carbon dioxide.
