FBA2 protein (Arabidopsis thaliana) - STRING interaction network
"FBA2" - Fructose-bisphosphate aldolase 2, chloroplastic in Arabidopsis thaliana
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 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
protein homology
Your Input:
Gene Fusion
FBA2Fructose-bisphosphate aldolase 2, chloroplastic; Protein is tyrosine-phosphorylated and its phosphorylation state is modulated in response to ABA in Arabidopsis thaliana seeds; Belongs to the class I fructose-bisphosphate aldolase family (398 aa)    
Predicted Functional Partners:
Sedoheptulose-1,7-bisphosphatase, chloroplastic; Encodes the chloroplast enzyme sedoheptulose-1,7-bisphosphatase (SBPase), involved in the carbon reduction of the Calvin cycle. Increase in SBPase activity in transgenic lines accumulate up to 50% more sucrose and starch than wild-type; Belongs to the FBPase class 1 family (393 aa)
Encodes chloroplast localized glyceraldehyde-3-phosphate dehydrogenase that can use both NADH and NADPH to reduce 1,3-diphosphate glycerate. It forms A2B2 heterotetramers with GapA forms of the GADPH enzyme. These complexes are active in the light under reducing conditions, but show reduced NADPH-dependent activity in response to oxidized thioredoxins and increased NAD(H)/NADP(H) ratios due to the formation of inactive A8B8 hexadecamers (447 aa)
Encodes one of the two subunits forming the photosynthetic glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and as such a constituent of the supramolecular complex with phosphoribulokinase (PRK) thought to be linked by a small peptide encoded by CP12-2. GapA-1 is coordinately expressed by light with PRK and CP12-2. The enzyme activity, tested in leaf protein extracts dropped significantly after external sucrose treatment for the photosynthetic GAPDH (NADPH-dependent) but not for the cytosolic GAPDH (NADH-dependent) (396 aa)
Glyceraldehyde-3-phosphate dehydrogenase GAPA2, chloroplastic; Involved in the photosynthetic reductive pentose phosphate pathway (Calvin-Benson cycle). Catalyzes the reduction of 1,3-diphosphoglycerate by NADPH (By similarity) (399 aa)
Encodes subunit K of photosystem I reaction center (130 aa)
Fructose-1,6-bisphosphatase 1, chloroplastic; Catalyzes the irreversible reaction from fructose-1,6- bisphosphate to fructose-6-phosphate and inorganic phosphate, to regenerate the primary CO(2) acceptor molecule, ribulose-1,5- bisphosphate (Probable). Involved in the regulation of photosynthetic electron flow and sucrose synthesis. Its activity is critical for normal plant development and important for the regulation of a wide range of metabolic processes (417 aa)
Phosphoribulokinase, chloroplastic; Phosphoribulokinase (PRK); Its function is described as protein binding, phosphoribulokinase activity, ATP binding; Involved in response to cold, defense response to bacterium, biosynthetic process, peptidyl-cysteine S-nitrosylation; Located in 8 components; Expressed in 24 plant structures; Expressed during 15 growth stages; Contains the following InterPro domains- Phosphoribulokinase/uridine kinase (InterPro-IPR006083), Phosphoribulokinase (InterPro-IPR006082); BEST Arabidopsis thaliana protein match is- uridine kinase-like 5 (TAIR-AT3G27440.1); Ha [...] (395 aa)
Photosystem I chlorophyll a/b-binding protein 3-1, chloroplastic; The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated, here photosystem I (273 aa)
Ribulose bisphosphate carboxylase/oxygenase activase, chloroplastic; Activation of RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase; EC involves the ATP-dependent carboxylation of the epsilon-amino group of lysine leading to a carbamate structure (474 aa)
Photosystem I reaction center subunit V, chloroplastic; Encodes subunit G of photosystem I, an 11-kDa membrane protein that plays an important role in electron transport between plastocyanin and PSI and is involved in the stability of the PSI complex. PSI-G subunit is bound to PSI-B and is in contact with Lhca1. The protein inserts into thylakoids by a direct or "spontaneous" pathway that does not involve the activities of any known chloroplast protein-targeting machinery. PSI-G appears to be directly or indirectly involved in the interaction between Photosystem I and plastocyanin (160 aa)
