STRING allows inspection of the interaction evidence for any given network. Choose any of the viewers above (disabled if not applicable in your network).
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.
colored nodes: query proteins and first shell of interactors
white nodes: second shell of interactors
empty nodes: proteins of unknown 3D structure
filled nodes: some 3D structure is known or predicted
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 each other.
from curated databases
Polyphosphate kinase (54 aa)
Predicted Functional Partners:
Exopolyphosphatase (494 aa)
Inorganic pyrophosphatase (175 aa)
Hypothetical protein (44 aa)
Hypothetical protein (47 aa)
Phosphate regulon sensor protein (434 aa)
Transcriptional regulator PhoB (229 aa)
Phosphate transporter ATP-binding protein; Part of the ABC transporter complex PstSACB involved in phosphate import. Responsible for energy coupling to the transport system (258 aa)
Chaperonin GroEL; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions (553 aa)
DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner (806 aa)
