STRING protein interaction 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.
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:
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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
putPProline:sodium symporter; Catalyzes the sodium-dependent uptake of extracellular L- proline. This protein is also capable of using lithium as the transport cation. Also catalyzes the uptake of propionate (502 aa)    
Predicted Functional Partners:
Rhh-type transcriptional regulator, proline utilization regulon repressor / proline dehydrogenase / delta 1-pyrroline-5-carboxylate dehydrogenase; Oxidizes proline to glutamate for use as a carbon and nitrogen source and also function as a transcriptional repressor of the put operon
Tryptophan synthase, beta subunit; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine
Tryptophan synthase, alpha subunit; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate
Mfs transporter, mhs family, proline/betaine transporter; Proton symporter that senses osmotic shifts and responds by importing osmolytes such as proline, glycine betaine, stachydrine, pipecolic acid, ectoine and taurine. It is both an osmosensor and an osmoregulator which is available to participate early in the bacterial osmoregulatory response
Para-aminobenzoate synthetase component i; Part of a heterodimeric complex that catalyzes the two-step biosynthesis of 4-amino-4-deoxychorismate (ADC), a precursor of p- aminobenzoate (PABA) and tetrahydrofolate. In the first step, a glutamine amidotransferase (PabA) generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by aminodeoxychorismate synthase (PabB) to produce ADC. PabB, in the absence of PabA, can catalyze the formation of ADC in the presence of exogenous ammonia
Dna polymerase ii; Thought to be involved in DNA repair and/or mutagenesis. Its processivity is enhanced by the beta sliding clamp (dnaN) and clamp loader
Belongs to the isocitrate and isopropylmalate dehydrogenases family
Beta-d-glucuronidase; Belongs to the glycosyl hydrolase 2 family
Poorly processive, error-prone DNA polymerase involved in translesion repair and untargeted mutagenesis Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by Pol IV. Exhibits no 3'-5' exonuclease (proofreading) activity . Overexpression of Pol IV results in increased frameshift mutagenesis. It is required for stationary-phase adaptive mutation, which provides the bacterium with flexibility in dealing with environmental stress, enhancing long- term survival and evolutionary fitness.

Alanine or glycine:cation symporter, agcs family; Uncharacterized transporter YaaJ; Inner membrane transport protein
