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

bfrAProbable bacterioferritin BfrA; Iron-storage protein, whose ferroxidase center binds Fe(2+) ions, oxidizes them by dioxygen to Fe(3+), and participates in the subsequent Fe(3+) oxide mineral core formation within the central cavity of the protein complex. (159 aa)    
Predicted Functional Partners:
bfrB
Bacterioferritin BfrB; Iron-storage protein that displays ferroxidase activity, catalyzing the oxidation of Fe(2+) ions into Fe(3+) ions, that can then be deposited as a ferric-oxide mineral core within the central cavity of the protein complex; Belongs to the ferritin family. Prokaryotic subfamily.
