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.

hemBPorphobilinogen 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). (335 aa)    
Predicted Functional Partners:
hemC
Porphobilinogen deaminase (hemC); Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps.
 
 0.999
hemL
Glutamate-1-semialdehyde aminotransferase (hemL); Similar to GB:M57676 SP:P30949 PID:143040 GB:AL009126 percent identity: 51.67; identified by sequence similarity; putative; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. HemL subfamily.
 
 
 0.997
hemD
Uroporphyrinogen III synthase (hemD); Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
 
 
 0.986
hemA
glutamyl-tRNA reductase (hemA); Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA).
 
  
 0.951
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.
  
  
 0.897
MJ_0642
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ0642.
     
 0.805
MJ_0140
Conserved hypothetical protein; Involved in the archaeal biosynthesis of heme. Catalyzes the oxiation of precorrin-2 into sirohydroclorin (By similarity). Belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family.
     
 0.736
thrS
threonyl-tRNA synthetase (thrS); Catalyzes the attachment of threonine to tRNA(Thr) in a two- step reaction: L-threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). Also activates L-serine, but does not detectably transfer it to tRNA(Thr). Edits incorrectly charged L-seryl-tRNA(Thr) via its editing domain. Has no activity on correctly acylated L-seryl-tRNA(Ser) or L-threonyl- tRNA(Thr). Deacylates correctly charged glycyl- tRNA(Gly), but not glycyl-tRNA(Gly)(2'-dA76) (the terminal 2'-OH of tRNA adenine 76 has been dehydroxylated) nor [...]
     
 0.708
pyrK
Cytochrome-c3 hydrogenase, gamma chain; Responsible for channeling the electrons from the oxidation of dihydroorotate from the FMN redox center in the PyrD type B subunit to the ultimate electron acceptor NAD(+).
     
 0.695
hisI
phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphohydrolase (hisIE); Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
