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

fixPCytochrome Cbb3; C-type cytochrome. Part of the cbb3-type cytochrome c oxidase complex. FixP subunit is required for transferring electrons from donor cytochrome c via its heme groups to FixO subunit. From there, electrons are shuttled to the catalytic binuclear center of FixN subunit where oxygen reduction takes place. The complex also functions as a proton pump. (290 aa)    
Predicted Functional Partners:
fixN
Cytochrome C oxidase; 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 or a quinol are transferred to the bimetallic center formed by a high-spin heme and copper B.

fbcH
Cytochrome C; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis. c1 functions as an electron donor to cytochrome c.

fixI
Nitrogen fixation protein FixI; FixI is a pump of a specific cation involved in symbiotic nitrogen fixation. The four proteins FixG, FixH, FixI, and FixS may participate in a membrane-bound complex coupling the FixI cation pump with a redox process catalyzed by FixG.
