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
betBBetaine aldehyde dehydrogenase, nad-dependent; Involved in the biosynthesis of the osmoprotectant glycine betaine. Catalyzes the reversible oxidation of betaine aldehyde to the corresponding acid. It is highly specific for betaine and has a significantly higher affinity for NAD than for NADP (490 aa)    
Predicted Functional Partners:
Choline dehydrogenase, a flavoprotein; Involved in the biosynthesis of the osmoprotectant glycine betaine. Catalyzes the oxidation of choline to betaine aldehyde and betaine aldehyde to glycine betaine at the same rate
Tetr/acrr family transcriptional regulator, transcriptional repressor of bet genes; Repressor involved in the biosynthesis of the osmoprotectant glycine betaine. It represses transcription of the choline transporter BetT and the genes of BetAB involved in the synthesis of glycine betaine
Choline/glycine/proline betaine transport protein; High-affinity uptake of choline driven by a proton-motive force
Mfs transporter, putative metabolite:h+ symporter; Inner membrane metabolite transport protein YdjE; Putative transport protein
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
Putative family 65 glycosyl hydrolase; In vitro catalyzes the phosphorolysis of D-kojibiose into beta-D-glucose 1-phosphate and D-glucose. No other disaccharides tested substitute for D-kojibiose. In the reverse direction disaccharides can be formed from beta-D-glucose 1-phosphate plus D-glucose, L-sorbose, D- sorbitol, L-iditol or 1,5-anhydro-D-glucitol, but with low efficiency. The beta-D-glucose 1-phosphate product is the substrate for YcjU (AC P77366), the next apparent enzyme in the putative biochemical pathway encoded in this locus (yjcM to ycjW)
DUF463 family protein, puatative P-loop NTPase; To H.influenzae HI_1637
annotation not available
Asp/glu_racemase family protein; Amino-acid racemase able to utilize a broad range of substrates. Highest activity is observed with L-homoserine and D- homoserine. Has tenfold lower activity against L-methionine, L-leucine, L-valine and L-histidine. Has low activity with L-norvaline, L- asparagine, D-methionine, L-aminobutyric acid, L-isoleucine, L-serine, L-norleucine, L-alanine, L-glutamine, LL-diaminopimelic acid and L- phenylalanine. Has no activity against ten L-amino acids (Thr, Glu, Asp, Arg, Lys, Tyr, Trp, Orn, Cit and Aad) . D-amino acids might be used as components of peptido [...]
Putative l-rhamnonate transporter; Belongs to the major facilitator superfamily. Phthalate permease family
