STRINGSTRING
PPC4 protein (Arabidopsis thaliana) - STRING interaction network
"PPC4" - Phosphoenolpyruvate carboxylase 4 in Arabidopsis thaliana
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

PPC4Phosphoenolpyruvate carboxylase 4; Encodes one of four Arabidopsis phosphoenolpyruvate (PEP) carboxylase proteins. But, it is more similar to bacterial PEP carboxylase than plant PEP carboxylase. Efforts to express this enzyme and to demonstrate its enzymatic activity in E.coli failed; Belongs to the PEPCase type 1 family (1032 aa)    
Predicted Functional Partners:
PCK2
Encodes a putative phosphoenolpyruvate carboxykinase (ATP-dependent) (670 aa)
         
  0.971
PCK1
Encodes a putative phosphoenolpyruvate carboxykinase (ATP-dependent) (671 aa)
         
  0.969
AT5G58330
Lactate/malate dehydrogenase family protein; The chloroplastic, NADP-dependent form is essential for the photosynthesis C4 cycle, which allows plants to circumvent the problem of photorespiration. In C4 plants, NADP-MDH activity acts to convert oxaloacetate to malate in chloroplasts of mesophyll cells for transport to the bundle sheath cells (Probable). Plays an essential role in the regulation of catalase activity and the accumulation of a hydrogen peroxide-dependent signal by transmitting the redox state of the chloroplast to other cell compartments; Belongs to the LDH/MDH superfamil [...] (443 aa)
         
  0.961
PPDK
Encodes a dual-targeted protein believed to act as a pyruvate, orthophosphate dikinase. These enzymes are normally associated with C4 photosynthesis which does not occur in Arabidopsis. However, PPDK may play a role in remobilizing nitrogen during leaf senescence in Arabidopsis. The product of the long transcript (.1 gene model) was shown to be targeted to the chloroplast, whereas the shorter transcript (no targeting sequence) accumulates in the cytosol. The two proteins were also found to be expressed in slightly different tissues (963 aa)
         
  0.946
ALDH11A3
Encodes a protein with non-phosphorylating NADP-dependent glyceraldehyde-3-phosphate dehydrogenase activity. The activity of the enzyme was determined from leaf extracts; the enzyme has not been purified to confirm activity (503 aa)
         
  0.891
MLS
Malate synthase; Does not seem to be essential for lipid utilization and gluconeogenesis in seedlings; Belongs to the malate synthase family (562 aa)
       
  0.890
FDH
Formate dehydrogenase, chloroplastic/mitochondrial; Catalyzes the NAD(+)-dependent oxidation of formate to carbon dioxide. Involved in the cell stress response; Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family. FDH subfamily (384 aa)
       
  0.859
At1g78050
Phosphoglycerate/bisphosphoglycerate mutase (PGM); Its function is described as intramolecular transferase activity, phosphotransferases, catalytic activity; Involved in response to nitrate, metabolic process; Located in chloroplast; Expressed in 18 plant structures; Expressed during 7 growth stages; Contains the following InterPro domains- Histidine phosphatase superfamily, clade-1 (InterPro-IPR013078), Phosphoglycerate/bisphosphoglycerate mutase, active site (InterPro-IPR001345), Phosphoglycerate mutase 1 (InterPro-IPR005952); BEST Arabidopsis thaliana protein match is- Phosphoglycer [...] (332 aa)

AT1G22170
Phosphoglycerate mutase family protein; Its function is described as intramolecular transferase activity, phosphotransferases, catalytic activity; Involved in glycolysis, metabolic process; Located in chloroplast; Expressed in 19 plant structures; Expressed during 8 growth stages; Contains the following InterPro domains- Histidine phosphatase superfamily, clade-1 (InterPro-IPR013078), Phosphoglycerate/bisphosphoglycerate mutase, active site (InterPro-IPR001345), Phosphoglycerate mutase 1 (InterPro-IPR005952); BEST Arabidopsis thaliana protein match is- phosphoglycerate/bisphosphoglycer [...] (334 aa)

PPC1
Phosphoenolpyruvate carboxylase 1; Through the carboxylation of phosphoenolpyruvate (PEP) it forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle. Contributes probably to the adaptation to inorganic phosphate (Pi) deprivation; Belongs to the PEPCase type 1 family (967 aa)
