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:
coxC-2Cytochrome c oxidase subunit III; ORF_ID:alr2516. (197 aa)
hesBHesB protein; May be required for efficient nitrogen fixation. (123 aa)
hesAHesA protein; May be required for efficient nitrogen fixation. (252 aa)
nifWNitrogen fixation protein; May protect the nitrogenase Fe-Mo protein from oxidative damage; Belongs to the NifW family. (105 aa)
nifXNitrogen fixation protein; ORF_ID:all1436; nifX gene product. (137 aa)
nifNNitrogenase olybdenum-iron protein; This protein may play a role in the biosynthesis of the prosthetic group of nitrogenase (FeMo cofactor); Belongs to the NifD/NifK/NifE/NifN family. (444 aa)
nifENitrogen Fe/Mo cofactor biosynthesis E; This protein may play a role in the biosynthesis of the prosthetic group of nitrogenase (FeMo cofactor); Belongs to the NifD/NifK/NifE/NifN family. (480 aa)
nifDNitrogenase molybdenum-iron protein alpha chain; This molybdenum-iron protein is part of the nitrogenase complex that catalyzes the key enzymatic reactions in nitrogen fixation. (497 aa)
nifHNitrogenase iron protein; The key enzymatic reactions in nitrogen fixation are catalyzed by the nitrogenase complex, which has 2 components: the iron protein and the molybdenum-iron protein. (295 aa)
nifBNitrogen fixation protein; Involved in the biosynthesis of the iron-molybdenum cofactor (FeMo-co or M-cluster) found in the dinitrogenase enzyme of the nitrogenase complex in nitrogen-fixing microorganisms. NifB catalyzes the crucial step of radical SAM-dependent carbide insertion that occurs concomitant with the insertion of a 9th sulfur and the rearrangement/coupling of two [4Fe-4S] clusters into a [8Fe-9S-C] cluster, the precursor to the M-cluster. (475 aa)
porProtochlorophyllide oxido-reductase; Phototransformation of protochlorophyllide (Pchlide) to chlorophyllide (Chlide). (329 aa)
coxB-2Cytochrome c oxidase subunit II; Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B). (327 aa)
coxA-2Cytochrome c oxidase subunit I; Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1-3 form the functional core of the enzyme complex. CO I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B. (559 aa)
alr3808Nutrient-stress induced DNA binding protein; Involved in protection of chromosomal DNA from damage under nutrient-limited and oxidative stress conditions. Binds heme (By similarity); Belongs to the Dps family. (184 aa)
petFFerredoxin I; Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions; Belongs to the 2Fe2S plant-type ferredoxin family. (99 aa)
nifZIron-sulfur cofactor synthesis protein; ORF_ID:asr1408; nifZ gene product. (95 aa)
nifV1Homocitrate synthase; This protein is a Fe-Mo-cofactor biosynthetic component; Belongs to the alpha-IPM synthase/homocitrate synthase family. (377 aa)
nifTNifT protein; ORF_ID:asr1409. (67 aa)
