STRINGSTRING
PEPC1 protein (Arabidopsis thaliana) - STRING interaction network
"PEPC1" - Pyridoxal phosphate phosphatase-related protein 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

PEPC1Pyridoxal phosphate phosphatase-related protein; Catalyzes the specific cleavage of pyrophosphate (279 aa)    
Predicted Functional Partners:
AT5G20790
Uncharacterized protein (193 aa)
     
   
  0.906
At1g73010
Phosphate starvation-induced gene 2; Catalyzes the specific cleavage of pyrophosphate (295 aa)
     
 
0.903
PDXH
Pyridoxin (pyrodoxamine) 5’-phosphate oxidase; Catalyzes the oxidation of either pyridoxine 5’- phosphate (PNP) or pyridoxamine 5’-phosphate (PMP) into pyridoxal 5’-phosphate (PLP). Involved in the PLP salvage pathway. Has a higher preference for PNP over PMP. May also catalyze the epimerization of the S- and R-forms of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration. This is a prerequisite for the S-specific NAD(P)H-hydrate dehydratase to allow the repair of both epimers of NAD(P)HX (530 aa)
     
 
    0.902
PDX2
Pyridoxine biosynthesis 2; Catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the biosynthesis of pyridoxal 5’-phosphate. The resulting ammonia molecule is channeled to the active site of PDX1. Involved in the indirect resistance to singlet oxygen- generating photosensitizers (255 aa)
         
    0.900
PLR1
Pyridoxal reductase 1; Catalyzes the reduction of pyridoxal (PL) with NADPH and oxidation of pyridoxine (PN) with NADP(+). Involved in the PLP salvage pathway (365 aa)
         
    0.900
RSR4
REDUCED SUGAR RESPONSE 4; Catalyzes the formation of pyridoxal 5’-phosphate from ribose 5-phosphate (RBP), glyceraldehyde 3-phosphate (G3P) and ammonia. The ammonia is provided by PDX2. Can also use ribulose 5- phosphate and dihydroxyacetone phosphate as substrates, resulting from enzyme-catalyzed isomerization of RBP and G3P, respectively. Also plays an indirect role in resistance to singlet oxygen- generating photosensitizers (309 aa)
         
    0.900
PDX1.2
Pyridoxine biosynthesis 1.2; The protein has no function in the formation of pyridoxal 5’-phosphate (314 aa)
         
    0.900
PDX1.1
Pyridoxine biosynthesis 1.1; Catalyzes the formation of pyridoxal 5’-phosphate from ribose 5-phosphate (RBP), glyceraldehyde 3-phosphate (G3P) and ammonia. The ammonia is provided by PDX2. Can also use ribulose 5- phosphate and dihydroxyacetone phosphate as substrates, resulting from enzyme-catalyzed isomerization of RBP and G3P, respectively. Also plays an indirect role in resistance to singlet oxygen- generating photosensitizers (309 aa)
         
    0.900
AT4G29530
Pyridoxal phosphate phosphatase-related protein; Catalyzes the specific cleavage of pyrophosphate (245 aa)
         
0.806
SOS4
Pyridoxal kinase; Catalyzes the transfer of a phosphate group from ATP to the 5-hydroxylmethyl group of pyridoxal to form the biologically active pyridoxal phosphate (343 aa)
         
    0.800
