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
Your Input:
qrcBMolybdopterin oxidoreductase, molybdopterin-binding subunit, putative; Component of the respiratory Qrc complex, that catalyzes the reduction of the menaquinone pool using electrons transferred from the reduced periplasmic cytochrome c3, and which is probably involved in sulfate respiration. Is likely essential for growth on H(2) or formate since the periplasmic hydrogenases and/or formate dehydrogenases act as primary electron donors for the Qrc complex. The function of the QrcB subunit is unknown; in the absence of a catalytic site, it may provide a structural scaffold for the other [...] (691 aa)

DVU_0624NapC/NirT cytochrome c family protein; Electron donor subunit of the cytochrome c nitrite reductase holocomplex NrfHA. Acquires electrons from the menaquinone pool and mediates their transfer to the catalytic subunit NrfA in an anaerobic respiratory process of nitrite. The other biological function of the NrfHA holocomplex is to detoxify nitrite. This function is essential for the survival of this organism as it enables it to overcome inhibition by nitrite, which is produced by other organisms living in the same environment (Probable). Belongs to the NapC/NirT/NrfH family. (159 aa)
qrcDMolybdopterin oxidoreductase, transmembrane subunit, putative; Component of the respiratory Qrc complex, that catalyzes the reduction of the menaquinone pool using electrons transferred from the reduced periplasmic cytochrome c3, and which is probably involved in sulfate respiration. Is likely essential for growth on H(2) or formate since the periplasmic hydrogenases and/or formate dehydrogenases act as primary electron donors for the Qrc complex. The QrcD subunit anchors the protein complex to the membrane and likely interacts with the quinone pool. (419 aa)
qrcCMolybdopterin oxidoreductase, iron-sulfur cluster-binding subunit, putative; Component of the respiratory Qrc complex, that catalyzes the reduction of the menaquinone pool using electrons transferred from the reduced periplasmic cytochrome c3, and which is probably involved in sulfate respiration. Is likely essential for growth on H(2) or formate since the periplasmic hydrogenases and/or formate dehydrogenases act as primary electron donors for the Qrc complex. QrcC is an electron- transferring subunit; its cubane iron sulfur clusters form a pathway for electron transfer between the he [...] (255 aa)
