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
Your Input:
ptsIPEP-protein phosphotransferase of PTS system (enzyme I); General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr). Can also use (Z)-3-fluoro-PEP (ZFPEP), (Z)-3-methyl- PEP (ZMePEP), (Z)-3-chloro-PEP (ZClPEP) and (E)-3-chloro-PEP (EClPEP) as alte [...] (575 aa)

Specific for elongation from C-10 to unsaturated C-16 and C-18 fatty acids; Belongs to the thiolase-like superfamily. Beta-ketoacyl-ACP synthases family. (406 aa)
lacZbeta-D-galactosidase; Protein involved in carbohydrate catabolic process; Belongs to the glycosyl hydrolase 2 family. (1024 aa)
ralRRac prophage; Toxic component of a type I toxin-antitoxin (TA) system. Upon overexpression inhibits growth and reduces colony-forming units in both the presence and absence of the Rac prophage, cells become filamentous. Has deoxyribonuclease activity (probably endonucleolytic), does not digest RNA. Its toxic effects are neutralized by sRNA antitoxin RalA, which is encoded in trans on the opposite DNA strand. Has RAL-like activity. (64 aa)
chbGChito-oligosaccharide deacetylase; ChbG is essential for growth on the acetylated chitooligosaccharides chitobiose and chitotriose but is dispensable for growth on cellobiose and chitosan dimer, the deacetylated form of chitobiose. Deacetylation of chitobiose-6-P and chitotriose-6-P is necessary for both the activation of the chb promoter by the regulatory protein ChbR and the hydrolysis of phosphorylated beta-glucosides by the phospho-beta-glucosidase ChbF. Catalyzes the removal of only one acetyl group from chitobiose-6-P to yield monoacetylchitobiose-6-P, the inducer of ChbR and the [...] (249 aa)
pspARegulatory protein for phage-shock-protein operon; The phage shock protein (psp) operon (pspABCDE) may play a significant role in the competition for survival under nutrient- or energy-limited conditions. PspA negatively regulates expression of the pspABCDE promoter and of pspG through negative regulation of the psp- specific transcriptional activator PspF. Is also required for membrane integrity, efficient translocation and maintenance of the proton motive force. Belongs to the PspA/IM30 family. (222 aa)
crrGlucose-specific enzyme IIA component of PTS; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II complex composed of PtsG and Crr is involved in glucose transport. The non-phosphorylated EIII-Glc is an inhibitor for uptake of certain sugars such as maltose, melibiose, lactose, and glycerol. Phosphorylated EIII-Glc, however, may be an activator for adenylate cyclase. It is an im [...] (169 aa)
srlRSorbitol-inducible srl operon transcriptional repressor; Regulator for gut (srl), glucitol operon; Protein involved in carbohydrate catabolic process, transcription and regulation of transcription, DNA-dependent. (257 aa)
ptsPPEP-protein phosphotransferase enzyme I; Component of the phosphoenolpyruvate-dependent nitrogen- metabolic phosphotransferase system (nitrogen-metabolic PTS), that seems to be involved in regulating nitrogen metabolism. Enzyme I-Ntr transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (NPr). Could function in the transcriptional regulation of sigma-54 dependent operons in conjunction with the NPr (PtsO) and EIIA-Ntr (PtsN) proteins. Enzyme I-Ntr is specific for NPr. (748 aa)
mtlAMannitol-specific PTS enzyme: IIA, IIB and IIC components; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in D-mannitol transport. Also able to use D-mannonic acid. (637 aa)
mtlDMannitol-1-phosphate dehydrogenase, NAD-dependent; Mannitol-1-phosphate dehydrogenase; Protein involved in carbohydrate catabolic process. (382 aa)
mtlRMannitol operon repressor; Involved in the repression of the expression of the mannitol mtlADR operon. Does not bind the operator/promoter regulatory region of this operon. Therefore, seems to belong to a new class of transcription factors in bacteria that may regulate gene expression indirectly, perhaps as a part of a larger transcriptional complex. (195 aa)
frwAPutative PTS enzyme: Hpr, enzyme I and II components; Multifunctional protein that includes general (non sugar- specific) and sugar-specific components of the phosphoenolpyruvate- dependent sugar phosphotransferase system (sugar PTS).

The enzyme II FrwABC PTS system is involved in fructose transport. (833 aa)
acsacetyl-CoA synthetase; Catalyzes the conversion of acetate into acetyl-CoA (AcCoA), an essential intermediate at the junction of anabolic and catabolic pathways. Acs undergoes a two-step reaction. In the first half reaction, Acs combines acetate with ATP to form acetyl-adenylate (AcAMP) intermediate. In the second half reaction, it can then transfer the acetyl group from AcAMP to the sulfhydryl group of CoA, forming the product AcCoA. (652 aa)
