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

hmdH2-forming N5,N10-methylene-tetrahydromethanopterin dehydrogenease; Catalyzes the reversible reduction of methenyl-H(4)MPT(+) to methylene-H(4)MPT. (354 aa)    
Predicted Functional Partners:
mtd
F420-dependent methylenetetrahydromethanopterin dehydrogenase; Catalyzes the reversible reduction of methenyl-H(4)MPT(+) to methylene-H(4)MPT.
     
 0.995
mch
N5,N10-methenyltetrahydromethanopterin cyclohydrolase; Catalyzes the reversible interconversion of 5-formyl-H(4)MPT to methenyl-H(4)MPT(+); Belongs to the MCH family.
   
 
 0.965
mer
Coenzyme F420-dependent N5,N10-methylenetetrahydromethanopterin reductase; Catalyzes the reversible reduction of methylene-H(4)MPT to methyl-H(4)MPT; Belongs to the mer family.

flpA
Conserved archaeal fibrillarin homolog; Citation: J Bacteriol 1994 176(7):2124-7.
  
  
 0.865
bioB
Biotin synthetase.
  
  
 0.791
ftr
Formylmethanofuran: tetrahydromethanopterin formyltransferase (Ftr); Catalyzes the reversible transfer of a formyl group from formylmethanofuran (formyl-MFR) to tetrahydromethanopterin (H(4)MPT) so as to produce 5-formyl tetrahydromethanopterin (5-formyl-H(4)MPT) and methanofuran (MFR); Belongs to the FTR family.

tyrA
Prephenate dehydrogenase; Citation: MacBeath G, Kast P, Hilvert D. (1998) Biochemistry 37:10062-73.
      
 0.735
ehaA
Conserved hypothetical protein; One of the integral membrane subunits of multisubunit membrane-bound [NiFe]-hydrogenase eha. Eha is predicted to form large electron transfer complex and might catalyze energy-driven reduction of low-potential redox carriers (By similarity).
      
 0.720
mcrA
Methyl-coenzyme M reductase I, alpha subunit; Component of the methyl-coenzyme M reductase (MCR) I that catalyzes the reductive cleavage of methyl-coenzyme M (CoM-S-CH3 or 2- (methylthio)ethanesulfonate) using coenzyme B (CoB or 7- mercaptoheptanoylthreonine phosphate) as reductant which results in the production of methane and the mixed heterodisulfide of CoB and CoM (CoM-S-S-CoB). This is the final step in methanogenesis.
      
 0.713
hdrB2
Heterodisulfide reductase; Part of a complex that catalyzes the reversible reduction of CoM-S-S-CoB to the thiol-coenzymes H-S-CoM (coenzyme M) and H-S-CoB (coenzyme B).
