STRINGSTRING
AT1G33320 protein (Arabidopsis thaliana) - STRING interaction network
"AT1G33320" - Pyridoxal phosphate 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

AT1G33320Pyridoxal phosphate (PLP)-dependent transferases superfamily protein; Catalyzes the first committed step of methionine (Met) biosynthesis. Catalyzes the formation of L-cystathionine from homoserine esters and L-cysteine, via a gamma-replacement reaction; Belongs to the trans-sulfuration enzymes family (412 aa)    
Predicted Functional Partners:
At3g03780
5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase 2; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation (765 aa)
   
 
  0.979
MS3
5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase 3, chloroplastic; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation (812 aa)
   
 
  0.979
ATMS1
5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase 1; Encodes a cytosolic cobalamin-independent methionine synthase, involved in methionine regeneration via the activated methyl cycle (SAM cycle). The protein undergoes thiolation following treatment with the oxidant tert-butylhydroperoxide (765 aa)
   
 
  0.976
HOG1
S-adenosyl-L-homocysteine hydrolase; Adenosylhomocysteine is a competitive inhibitor of S- adenosyl-L-methionine-dependent methyl transferase reactions; therefore adenosylhomocysteinase may play a key role in the control of methylations via regulation of the intracellular concentration of adenosylhomocysteine. Required for DNA methylation-dependent gene silencing (485 aa)
     
  0.957
SAHH2
S-adenosyl-l-homocysteine (SAH) hydrolase 2; Adenosylhomocysteine is a competitive inhibitor of S- adenosyl-L-methionine-dependent methyl transferase reactions; therefore adenosylhomocysteinase may play a key role in the control of methylations via regulation of the intracellular concentration of adenosylhomocysteine (485 aa)
     
  0.957
CPNIFS
Chloroplastic NIFS-like cysteine desulfurase; Catalyzes the removal of elemental sulfur and selenium atoms from L-cysteine, L-cystine, L-selenocysteine, and L- selenocystine to produce L-alanine. Supplies the inorganic sulfur for iron-sulfur (Fe-S) clusters. Required for the maturation of all plastidic Fe-S proteins and, thus, essential for plant growth; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family (463 aa)
   
 
  0.954
HMT2
Homocysteine S-methyltransferase 2; Encodes a homocysteine methyltransferase (HMT). Among the three HMT coding genes in the genome, HMT2 is responsible for a significant proportion of HMT activity in the flower stalks and silique hulls. However, HMT2 does not significantly contribute to the total HMT activity in seeds (333 aa)
   
 
  0.951
HMT-1
Homocysteine S-methyltransferase family protein; Catalyzes methyl transfer from S-methylmethionine (SMM) to adenosyl-L-homocysteine (AdoMet). SMM degradation (by HMT-1, HMT-2 and HMT-3) and biosynthesis (by MMT1) constitute the SMM cycle in plants, which is probably required to achieve short term control of AdoMet level (326 aa)
   
 
  0.951
HMT3
Homocysteine S-methyltransferase 3; Catalyzes methyl transfer from S-methylmethionine (SMM) to adenosyl-L-homocysteine (AdoMet). SMM degradation (by HMT-1, HMT-2 and HMT-3) and biosynthesis (by MMT1) constitute the SMM cycle in plants, which is probably required to achieve short term control of AdoMet level (347 aa)
   
 
  0.951
SIR
Assimilatory sulfite reductase (ferredoxin), chloroplastic; Essential protein with sulfite reductase activity required in assimilatory sulfate reduction pathway during both primary and secondary metabolism and thus involved in development and growth; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family (642 aa)
