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
hdhA7-alpha-hydroxysteroid dehydrogenase, NAD-dependent; Catalyzes the oxidation of the 7-alpha-hydroxy group of primary bile acids such as cholate, chenodeoxycholate and taurochenodeoxycholate . To a lesser extent, also able to use taurocholate and glycocholate (255 aa)    
Predicted Functional Partners:
Laci family transcriptional regulator, maltose regulon regulatory protein; Repressor for the malX and malY genes. Also regulates its own expression. Binds maltose as an inducer
3-hydroxyacyl-CoA dehydrogenase / enoyl-CoA hydratase / 3-hydroxybutyryl-CoA epimerase; Catalyzes the formation of a hydroxyacyl-CoA by addition of water on enoyl-CoA. Also exhibits 3-hydroxyacyl-CoA epimerase and 3- hydroxyacyl-CoA dehydrogenase activities. Strongly involved in the anaerobic degradation of long and medium-chain fatty acids in the presence of nitrate and weakly involved in the aerobic degradation of long-chain fatty acids
Tetr/acrr family transcriptional regulator, repressor for uid operon; Repressor for the uidRABC (gusRABC) operon
Melibiose:h(+)/na(+)/li(+) symporter; Responsible for melibiose and other galactoside transport. It is capable of using hydrogen, sodium, and lithium cations as coupling cations for cotransport, depending on the particular sugar transported (symport system)
DUF386 domain-containing evolved beta-D-galactosidase subunit beta; Required for full activity of the EbgA enzyme. Exact function not known
Putative zinc-binding dehydrogenase yggp; To K.pneumoniae SorE
Putative nad(p)-binding oxidoreductase; Catalyzes the NAD(P)H-dependent reduction of pyridoxal to pyridoxine in vitro. Is not able to reduce 4-pyridoxate, and to oxidize pyridoxine or pyridoxamine . Has Kemp eliminase activity towards the non-physiological substrate 5-nitrobenzisoxazole, producing 4-nitro-2-cyanophenol; this activity is not considered to be physiologically relevant
Uncharacterized oxidoreductase YbbO; Putative enzyme; Not classified; Belongs to the short-chain dehydrogenases/reductases (SDR) family
Autotransporter adhesin-related protein; Uncharacterized protein YdhQ; Possible enzyme
L-threonine 3-dehydrogenase, nad(p)-binding; Catalyzes the NAD(+)-dependent oxidation of L-threonine to 2- amino-3-ketobutyrate. To a lesser extent, also catalyzes the oxidation of D-allo-threonine and L-threonine amide, but not that of D-threonine and L-allothreonine. Cannot utilize NADP(+) instead of NAD(+)
