STRINGSTRING
UGP1 protein (Arabidopsis thaliana) - STRING interaction network
"UGP1" - UTP--glucose-1-phosphate uridylyltransferase 2 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

UGP1UTP--glucose-1-phosphate uridylyltransferase 2; Converts glucose 1-phosphate to UDP-glucose, which is the major glycosyl donor for polysaccharides. Acts redundantly with UGP1 and is essential for the synthesis of sucrose, starch and cell wall, and callose deposition; Belongs to the UDPGP type 1 family (469 aa)    
Predicted Functional Partners:
PGMP
Phosphoglucomutase, chloroplastic; Encodes a plastid isoform of the enzyme phosphoglucomutase involved in controlling photosynthetic carbon flow. Effective petiole movement against the direction of the gravity requires functional PGM activity that is required for full development of amyloplasts (623 aa)

AT5G18200
UTP-galactose-1-phosphate uridylyltransferases;ribose-5-phosphate adenylyltransferases; Catalyzes the conversion of ADP-glucose and inorganic phosphate (Pi) into glucose-1-phosphate and ADP. Does not possess galactose-1-phosphate uridylyltransferase activity (351 aa)
     
  0.992
PGM3
Phosphoglucomutase/phosphomannomutase family protein; Encodes a cytosolic phosphoglucomutase (PGM). Two Arabidopsis PGM proteins (AT1G70730/PGM2 and AT1G23190/PGM3) have high sequence similarities and redundant functions. Mature plants possessing a single cPGM allele had a major reduction in cPGM activity. Whereas pgm2 and pgm3 single mutants are undistinguishable from the wild type, loss of both PGM2 and PGM3 severely impairs male and female gametophyte development (583 aa)
 
 
 
  0.991
PHS2
Alpha-glucan phosphorylase 2, cytosolic; Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties (By similarity) (841 aa)
     
 
  0.977
PGM2
Phosphoglucomutase/phosphomannomutase family protein; Encodes a cytosolic phosphoglucomutase (PGM). Two Arabidopsis PGM proteins (AT1G70730/PGM2 and AT1G23190/PGM3) have high sequence similarities and redundant functions. Mature plants possessing a single cPGM allele had a major reduction in cPGM activity. Whereas pgm2 and pgm3 single mutants are undistinguishable from the wild type, loss of both PGM2 and PGM3 severely impairs male and female gametophyte development (662 aa)

AT3G29320
Glycosyl transferase, family 35; Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties (By similarity). May be not required for the degradation of starch, but the phosphorolysis of starch may play an important role in water stress tolerance (962 aa)

ADG1
Glucose-1-phosphate adenylyltransferase small subunit, chloroplastic; Encodes the small subunit of ADP-glucose pyrophosphorylase. The small subunit is the catalytic isoform responsible for ADP-glucose pyrophosphorylase activity. The presence of the small subunit is required for large subunit stability. Two isoforms of the small subunit (ApS1 and ApS2) have been described. ApS1 is the major small subunit isoform present in all plant tissues tested (520 aa)
   
 
  0.972
APL3
Glucose-1-phosphate adenylyltransferase large subunit 3, chloroplastic; Encodes the large subunit of ADP-Glucose Pyrophosphorylase which catalyzes the first, rate limiting step in starch biosynthesis. The large subunit plays a regulatory role whereas the small subunit (ApS) is the catalytic isoform. Four isoforms (ApL1-4) have been identified. ApL3 is the major large subunit isoform present in inflorescences, fruits and roots (521 aa)
   
 
  0.971
USP
UDP-sugar pyrophosphorylase; Required for the synthesis of the intine, the pectocellulosic inner wall of developing pollen. May function as the terminal enzyme of the myo-inositol oxidation (MIO) pathway. May also play a role in the salvage pathway for synthesis of nucleotide sugars. Can use a wide range of substrates including glucose-1-phosphate, galactose-1-phosphate, xylose-1-phosphate, arabinose-1-phosphate and glucuronate-1-phosphate (614 aa)
     
 
  0.970
APL1
Glucose-1-phosphate adenylyltransferase large subunit 1, chloroplastic; Encodes the large subunit of ADP-glucose pyrophosphorylase which catalyzes the first, rate limiting step in starch biosynthesis. The large subunit plays a regulatory role whereas the small subunit (ApS) is the catalytic isoform. Four isoforms (ApL1-4) have been identified. ApL1 is the major large subunit isoform present in leaves. Mutational analysis of APS1 suggests that APL1 and APL2 can compensate for loss of APS1 catalytic activity,suggesting both have catalytic as well as regulatory functions (522 aa)
