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

cfbDVanadium nitrogenase-associated protein N; 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 both the six-electron reduction of the tetrahydroporphyrin ring system and the gamma-lactamization of the c- acetamide side chain of Ni-sirohydrochlorin a,c-diamide to yield 15,17(3)-seco-F430-17(3)-acid (seco-F430), the last intermediate in the biosynthesis of the coenzyme F430; Belongs to the NifD/NifK/NifE/NifN family. (352 aa)    
Predicted Functional Partners:
cfbE
Conserved hypothetical protein; 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 activation the g-propionate side chain of 15,17(3)-seco-F430-17(3)-acid (seco-F430) for intramolecular C-C bond formation to yield the carbocyclic F ring of coenzyme F430. Belongs to the MurCDEF family.
