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

Catalyzes the interconversion of L-ribulose 5-phosphate (LRu5P) and D- xylulose 5-phosphate (D-Xu5P) via a retroaldol/aldol mechanism (carbon- carbon bond cleavage analogous to a class II aldolase reaction).

galKGalactokinase; Catalyzes the transfer of the gamma-phosphate of ATP to D- galactose to form alpha-D-galactose-1-phosphate (Gal-1-P). To a lesser extent, is also able to phosphorylate 2-deoxy-D-galactose and D- galactosamine. Is not able to use D-galacturonic acid, D-talose, L- altrose, and L-glucose as substrates. (382 aa)
modAMolybdate ABC transporter periplasmic binding protein; Part of the ABC transporter complex ModABC involved in the transport of molybdenum into the cell. Binds molybdate with high affinity in vitro and with a similar affinity in vivo. Binds tungstate with high affinity in vitro. Binds unnatural anion perrhenate with high affinity in vitro. Does not bind sulfate, phosphate, arsenate, selenate, chlorate, metavanadate, nitrate, perchlorate, permanganate or carbonate. Belongs to the bacterial solute-binding protein ModA family. (257 aa)
moaAMolybdopterin biosynthesis protein A; Catalyzes, together with MoaC, the conversion of 5'-GTP to cyclic pyranopterin monophosphate (cPMP or molybdopterin precursor Z). (329 aa)
narKNitrate/nitrite transporter; Catalyzes nitrate uptake, nitrite uptake and nitrite export across the cytoplasmic membrane. Functions as a nitrate/nitrite exchanger, and protons are probably not co-transported with the substrate. (463 aa)
narGNitrate reductase 1, alpha subunit; The nitrate reductase enzyme complex allows E.coli to use nitrate as an electron acceptor during anaerobic growth. The alpha chain is the actual site of nitrate reduction. (1247 aa)
narHNitrate reductase 1, beta (Fe-S) subunit; The nitrate reductase enzyme complex allows E.coli to use nitrate as an electron acceptor during anaerobic growth. The beta chain is an electron transfer unit containing four cysteine clusters involved in the formation of iron-sulfur centers. Electrons are transferred from the gamma chain to the molybdenum cofactor of the alpha subunit. (512 aa)
narJMolybdenum-cofactor-assembly chaperone delta subunit of nitrate reductase 1; Chaperone required for proper molybdenum cofactor insertion and final assembly of the membrane-bound respiratory nitrate reductase 1. Required for the insertion of the molybdenum into the apo-NarG subunit, maybe by keeping NarG in an appropriate competent-open conformation for the molybdenum cofactor insertion to occur. NarJ maintains the apoNarGH complex in a soluble state. Upon insertion of the molybdenum cofactor, NarJ seems to dissociate from the activated soluble NarGH complex, before its association with [...] (236 aa)
narINitrate reductase 1, gamma (cytochrome b(NR)) subunit; The nitrate reductase enzyme complex allows E.coli to use nitrate as an electron acceptor during anaerobic growth. The gamma chain is a membrane-embedded heme-iron unit resembling cytochrome b, which transfers electrons from quinones to the beta subunit. (225 aa)
edaKHG/KDPG aldolase; Involved in the degradation of glucose via the Entner- Doudoroff pathway. Catalyzes the reversible, stereospecific retro-aldol cleavage of 2-Keto-3-deoxy-6-phosphogluconate (KDPG) to pyruvate and D- glyceraldehyde-3-phosphate. In the synthetic direction, it catalyzes the addition of pyruvate to electrophilic aldehydes with si-facial selectivity. It accepts some nucleophiles other than pyruvate, including 2-oxobutanoate, phenylpyruvate, and fluorobutanoate. It has a preference for the S-configuration at C2 of the electrophile. (213 aa)
amyACytoplasmic alpha-amylase; Protein involved in carbohydrate catabolic process and polysaccharide catabolic process; Belongs to the glycosyl hydrolase 13 family. (495 aa)
xylBXylulokinase; Catalyzes the phosphorylation of D-xylulose to D-xylulose 5- phosphate. Also catalyzes the phosphorylation of 1- deoxy-D-xylulose to 1-deoxy-D-xylulose 5-phosphate, with lower efficiency. Can also use D-ribulose, xylitol and D- arabitol, but D-xylulose is preferred over the other substrates. Has a weak substrate-independent Mg-ATP-hydrolyzing activity ; Belongs to the FGGY kinase family. (484 aa)
malSAlpha-amylase; Since only maltooligosaccharides up to a chain length of 6 glucose units are actively transported through the cytoplasmic membrane via the membrane-bound complex of three proteins, MalF, MalG, and MalK, longer maltooligosaccharides must first be degraded by the periplasmic alpha-amylase, the MalS protein; Belongs to the glycosyl hydrolase 13 family. (676 aa)
rbsAD-ribose ABC transporter ATPase; Part of the ABC transporter complex RbsABC involved in ribose import. Responsible for energy coupling to the transport system. Belongs to the ABC transporter superfamily. Ribose importer (TC 3.A.1.2.1) family. (501 aa)
rbsCD-ribose ABC transporter permease; Part of the ABC transporter complex RbsABC involved in ribose import. Probably responsible for the translocation of the substrate across the membrane. (321 aa)
rbsKRibokinase; Catalyzes the phosphorylation of ribose at O-5 in a reaction requiring ATP and magnesium. The resulting D-ribose-5-phosphate can then be used either for sythesis of nucleotides, histidine, and tryptophan, or as a component of the pentose phosphate pathway. Belongs to the carbohydrate kinase PfkB family. Ribokinase subfamily. (309 aa)
rbsRTranscriptional repressor of ribose metabolism; Transcriptional repressor for the ribose rbsDACBK operon. RbsR binds to a region of perfect dyad symmetry spanning the rbs operon transcriptional start site. The affinity for the rbs operator is reduced by addition of ribose, consistent with ribose being the inducer of the operon. (330 aa)
ilvDDihydroxyacid dehydratase. (616 aa)
pfkA6-phosphofructokinase I; Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis; Belongs to the phosphofructokinase type A (PFKA) family.
