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

Gene Fusion
mgsAMethylglyoxal synthase; Catalyzes the formation of methylglyoxal from dihydroxyacetone phosphate (152 aa)    
Predicted Functional Partners:
L-1,2-propanediol dehydrogenase/glycerol dehydrogenase; 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 ethy [...]
Nadph-dependent aldehyde reductase yqhd; NADP-dependent ADH activity
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
Glyoxalase i, ni-dependent; Catalyzes the isomerization of the hemithioacetal formed spontaneously from methylglyoxal and glutathione, to S- lactoylglutathione, which is then hydrolyzed by a type II glyoxalase (GloB or GloC). Is involved in methylglyoxal (MG) detoxification (Probable). Involved in resistance to hypochlorous acid (HOCl), which is the active component of household bleach and a powerful antimicrobial during the innate immune response
L-1,2-propanediol oxidoreductase; Belongs to the iron-containing alcohol dehydrogenase family
Dephospho-coa kinase; Catalyzes the phosphorylation of the 3'-hydroxyl group of dephosphocoenzyme A to form coenzyme A
Fermentative d-lactate dehydrogenase, nad-dependent; Fermentative lactate dehydrogenase
Bira family transcriptional regulator, biotin operon repressor / biotin---[acetyl-coa-carboxylase] ligase; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon
Hydroxyacylglutathione hydrolase glob; Type II glyoxalase that catalyzes the hydrolysis of (R)-S- lactoylglutathione to (R)-lactate and glutathione Is more efficient than the isozyme GloC, and plays a major contribution to methylglyoxal (MG) detoxification in E.coli . The two isoenzymes have additive effects and ensure maximal MG degradation
Glutathione-regulated potassium-efflux system ancillary protein kefc; Pore-forming subunit of a potassium efflux system that confers protection against electrophiles. Catalyzes K(+)/H(+) antiport. Can also export rubidium, lithium and sodium
