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

MJ_0140Conserved 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. (206 aa)    
Predicted Functional Partners:
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.
 
 
 0.993
cbiX
Conserved hypothetical protein; Catalyzes the insertion of Co(2+) into sirohydrochlorin as part of the anaerobic pathway to cobalamin biosynthesis. Involved in the biosynthesis of the unique nickel-containing tetrapyrrole coenzyme F430, the prosthetic group of methyl-coenzyme M reductase (MCR), which plays a key role in methanogenesis and anaerobic methane oxidation. Catalyzes the insertion of Ni(2+) into sirohydrochlorin to yield Ni- sirohydrochlorin.
  
 
 0.990
hemA
glutamyl-tRNA reductase (hemA); Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA).
 
   
 0.972
cbiL
Cobalamin biosynthesis precorrin-2 methyltransferase (cbiL); Methylates cobalt-precorrin-2 at the C-20 position to produce cobalt-precorrin-3A in the anaerobic cobalamin biosynthesis pathway.
    
 0.967
MJ_1241
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ1241.
  
  
 0.835
hemD
Uroporphyrinogen III synthase (hemD); Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
 
  
 0.808

 0.805
MJ_0142
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 29.84; identified by sequence similarity; putative; Belongs to the UPF0332 family.
       0.800
MJ_0141
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 36.84; identified by sequence similarity; putative; Belongs to the M.jannaschii MJ0126/MJ0128/MJ0141/MJ0435/MJ0604/MJ1215/MJ1217/MJ1305/MJ1379 family.
       0.778
cobS
Cobalamin (5'-phosphate) synthase (cobS); Joins adenosylcobinamide-GDP and alpha-ribazole to generate adenosylcobalamin (Ado-cobalamin). Also synthesizes adenosylcobalamin 5'-phosphate from adenosylcobinamide-GDP and alpha-ribazole 5'- phosphate; Belongs to the CobS family.
