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:
a 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
bdhAAcetoin reductase/2,3-butanediol dehydrogenase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme. (346 aa)    
Predicted Functional Partners:
Alpha-acetolactate decarboxylase; Converts acetolactate into acetoin, which can be excreted by the cells. This may be a mechanism for controlling the internal pH of cells in the stationary stage; Belongs to the alpha-acetolactate decarboxylase family.
Transcriptional regulator controlling alsSD and ictEP expression (LysR family); Regulates the expression of the alsSD operon for acetoin biosynthesis.
Alpha-acetolactate synthase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.
Acetoin dehydrogenase E1 component (TPP-dependent alpha subunit); Catalyzes the 2,6-dichlorophenolindophenol-dependent cleavage of acetoin into acetate and acetaldehyde. The alpha subunit is probably the catalytic subunit of the enzyme (By similarity).
Transcriptional regulator (Lacl family); Global transcriptional regulator of carbon catabolite repression (CCR) and carbon catabolite activation (CCA), which ensures optimal energy usage under diverse conditions. Interacts with either P- Ser-HPr or P-Ser-Crh, leading to the formation of a complex that binds to DNA at the catabolite-response elements (cre). Binding to DNA allows activation or repression of many different genes and operons.
L-lactate dehydrogenase; Catalyzes the conversion of lactate to pyruvate.
Transcriptional regulator; Activates, in anaerobic conditions, the transcription of the fermentative operons lctEP and alsDS, of the hmp gene encoding a flavohemoglobin-like protein, the nitrite reductase operon nasDE and the heme biosynthesis genes hemN and hemZ.
Putative formate dehydrogenase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; In the C-terminal section; belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
Transcriptional regulator (FNR/CAP family); It is involved in the activation of genes necessary for anaerobic respiration.
Putative oxidoreductase; Putative nitroreductase that may contribute to the degradation of aromatic compounds.
