STRINGSTRING
STRING protein interaction network
Nodes:
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:
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
Others
textmining
co-expression
protein homology

gldAGlycerol dehydrogenase, NAD+ dependent; Catalyzes the NAD-dependent oxidation of glycerol to dihydroxyacetone (glycerone). Allows microorganisms to utilize glycerol as a source of carbon under anaerobic conditions. In E.coli, an important role of GldA is also likely to regulate the intracellular level of dihydroxyacetone by catalyzing the reverse reaction, i.e. the conversion of dihydroxyacetone into glycerol. Possesses a broad substrate specificity, since it is also able to oxidize 1,2-propanediol and to reduce glycolaldehyde, methylglyoxal and hydroxyacetone into ethylene glycol, lac [...] (367 aa)    
Predicted Functional Partners:
mgsA
Methylglyoxal synthase; Catalyzes the formation of methylglyoxal from dihydroxyacetone phosphate.
     
 0.990
glpK
Glycerol kinase; Key enzyme in the regulation of glycerol uptake and metabolism. Catalyzes the phosphorylation of glycerol to yield sn- glycerol 3-phosphate. It also catalyzes the phosphorylation of dihydroxyacetone, L-glyceraldehyde and D-glyceraldehyde. It uses only ATP; Belongs to the FGGY kinase family.
     
 0.989
fucO
L-1,2-propanediol oxidoreductase; Protein involved in carbohydrate catabolic process and glycolate metabolic process; Belongs to the iron-containing alcohol dehydrogenase family.
 
 
 0.986
yqhD
Aldehyde reductase, NADPH-dependent; NADP-dependent ADH activity; Belongs to the iron-containing alcohol dehydrogenase family.
     
 0.979
dhaM
Putative dihydroxyacetone-specific PTS enzymes: HPr, EI components; Component of the dihydroxyacetone kinase complex, which is responsible for the phosphoenolpyruvate (PEP)-dependent phosphorylation of dihydroxyacetone. DhaM serves as the phosphoryl donor. Is phosphorylated by phosphoenolpyruvate in an EI- and HPr-dependent reaction, and a phosphorelay system on histidine residues finally leads to phosphoryl transfer to DhaL and dihydroxyacetone.
    
 0.957
dhaL
Dihydroxyacetone kinase, C-terminal domain; ADP-binding subunit of the dihydroxyacetone kinase, which is responsible for the phosphoenolpyruvate (PEP)-dependent phosphorylation of dihydroxyacetone. DhaL-ADP is converted to DhaL- ATP via a phosphoryl group transfer from DhaM and transmits it to dihydroxyacetone bound to DhaK. DhaL acts also as coactivator of the transcription activator DhaR by binding to the sensor domain of DhaR. In the presence of dihydroxyacetone, DhaL-ADP displaces DhaK and stimulates DhaR activity. In the absence of dihydroxyacetone, DhaL-ADP is converted by the PT [...]

yahK
Broad specificity NADPH-dependent aldehyde reductase, Zn-containing; Catalyzes the reduction of a wide range of aldehydes into their corresponding alcohols. Has a strong preference for NADPH over NADH as the electron donor. Cannot use a ketone as substrate. Is a major source of NADPH-dependent aldehyde reductase activity in E.coli. The in vivo functions of YahK has yet to be determined. Belongs to the zinc-containing alcohol dehydrogenase family.

dhaK
Dihydroxyacetone kinase, PTS-dependent, dihydroxyacetone-binding subunit; Dihydroxyacetone binding subunit of the dihydroxyacetone kinase, which is responsible for the phosphoenolpyruvate (PEP)- dependent phosphorylation of dihydroxyacetone via a phosphoryl group transfer from DhaL-ATP. Binds covalently dihydroxyacetone in hemiaminal linkage. DhaK acts also as corepressor of the transcription activator DhaR by binding to the sensor domain of DhaR. In the presence of dihydroxyacetone, DhaL-ADP displaces DhaK and stimulates DhaR activity. In the absence of dihydroxyacetone, DhaL- ADP is [...]

ydjG
Methylglyoxal reductase, NADH-dependent; Catalyzes the NADH-dependent reduction of methylglyoxal (2- oxopropanal) in vitro. It is not known if this activity has physiological significance. Cannot use NADPH as a cosubstrate. Seems to play some role in intestinal colonization.

adhE
Acetaldehyde dehydrogenase [acetylating]; This enzyme has three activities: ADH, ACDH, and PFL- deactivase. In aerobic conditions it acts as a hydrogen peroxide scavenger. The PFL deactivase activity catalyzes the quenching of the pyruvate-formate-lyase catalyst in an iron, NAD, and CoA dependent reaction; In the N-terminal section; belongs to the aldehyde dehydrogenase family.
