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

hemDUroporphyrinogen III synthase (hemD); Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III. (240 aa)    
Predicted Functional Partners:
hemC
Porphobilinogen deaminase (hemC); Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps.
 0.999
cobA
uroporphyrin-III C-methyltransferase (cobA); Catalyzes both methylations at C-2 and C-7 of uroporphyrinogen III leading to precorrin-1 and precorrin-2; their oxidative esterification gives respectively factor I octamethyl ester and sirohydrochlorin.
 
 0.997
hemB
Porphobilinogen synthase (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).
 
 
 0.964
MJ_0235
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ0235.
  
    0.962
cbiF
Cobalamin biosynthesis precorrin-3 methylase (cbiF); Catalyzes the methylation of C-11 in cobalt-precorrin-4 to form cobalt-precorrin-5A.
    
 0.953
MJ_0995
VAR1 protein isolog; Similar to GP:343962 percent identity: 26.19; identified by sequence similarity; putative.
       0.952
MJ_1458
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 58.60; identified by sequence similarity; putative.
  
    0.899
hemA
glutamyl-tRNA reductase (hemA); Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA).
 
  
 0.878
trkA
TRK system potassium uptake protein (trkA); Part of a potassium transport system.
  
    0.876
MJ_0993
Hydrogenase expression/formation protein (hypD); Similar to SP:P31903 GB:X70183 PID:38775 percent identity: 42.46; identified by sequence similarity; putative; Belongs to the HypD family.
