STRINGSTRING
CYP97A3 protein (Arabidopsis thaliana) - STRING interaction network
"CYP97A3" - Cytochrome P450, family 97, subfamily A, polypeptide 3 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

CYP97A3Cytochrome P450, family 97, subfamily A, polypeptide 3; Heme-containing cytochrome P450 involved in the biosynthesis of xanthophylls. Specific for beta-ring hydroxylation of alpha- and beta-carotene. Has also a low activity toward the epsilon-rings of alpha-carotene. The beta-ring of alpha-carotene is the preferred substrate in planta (595 aa)    
Predicted Functional Partners:
CHY2
Beta-carotene 3-hydroxylase 2, chloroplastic; Nonheme diiron monooxygenase involved in the biosynthesis of xanthophylls. Specific for beta-ring hydroxylations of beta-carotene. Has also a low activity toward the beta- and epsilon-rings of alpha-carotene. No activity with acyclic carotenoids such as lycopene and neurosporene. Uses ferredoxin as an electron donor (Probable); Belongs to the sterol desaturase family (303 aa)

At4g25700
Beta-carotene 3-hydroxylase 1, chloroplastic; Nonheme diiron monooxygenase involved in the biosynthesis of xanthophylls. Specific for beta-ring hydroxylations of beta-carotene. Has also a low activity toward the beta- and epsilon-rings of alpha-carotene. No activity with acyclic carotenoids such as lycopene and neurosporene. Uses ferredoxin as an electron donor (Probable); Belongs to the sterol desaturase family (310 aa)
     
 
  0.993
ABA1
Zeaxanthin epoxidase, chloroplastic; Zeaxanthin epoxidase that plays an important role in the xanthophyll cycle and abscisic acid (ABA) biosynthesis. Converts zeaxanthin into antheraxanthin and subsequently violaxanthin. Required for resistance to osmotic and drought stresses, ABA- dependent stomatal closure, seed development and dormancy, modulation of defense gene expression and disease resistance and non-photochemical quencing (NPQ). Through its role in ABA biosynthesis, regulates the expression of stress-responsive genes such as RD29A during osmotic stress and is required for norma [...] (667 aa)
     
  0.980
LYC
Lycopene beta cyclase, chloroplastic; Encodes a protein with lycopene β-cyclase activity. This enzyme uses the linear, symmetrical lycopene as substrate. However, unlike the ε-cyclase which adds only one ring, the β-cyclase introduces a ring at both ends of lycopene to form the bicyclic β-carotene (501 aa)
     
 
  0.972
LUT2
Lycopene epsilon cyclase, chloroplastic; Catalyzes the single epsilon-cyclization reaction which converts lycopene to delta-carotene and neurosporene to alpha- zeacarotene. Required for lutein biosynthesis (524 aa)
     
   
  0.954
NPQ1
Violaxanthin de-epoxidase, chloroplastic; Part of the xanthophyll (or violaxanthin) cycle for controlling the concentration of zeaxanthin in chloroplasts. Catalyzes the two-step mono de-epoxidation reaction. Stereospecific for all-trans xanthophylls. Zeaxanthin induces the dissipation of excitation energy in the chlorophyll of the light- harvesting protein complex of photosystem II; Belongs to the calycin superfamily. Lipocalin family (462 aa)
     
 
  0.953
LUT1
Carotene epsilon-monooxygenase, chloroplastic; Heme-containing cytochrome P450 involved in the biosynthesis of xanthophylls. Specific for epsilon- and beta-ring hydroxylation of alpha-carotene. Has only a low activity toward the beta-rings of beta-carotene. The preferred substrate in planta is not alpha-carotene but the epsilon-ring of zeinoxanthin (539 aa)
   
 
0.944
PSY
Phytoene synthase, chloroplastic; Catalyzes the reaction from prephytoene diphosphate to phytoene; Belongs to the phytoene/squalene synthase family (437 aa)
   
 
  0.926
D27
Beta-carotene isomerase D27, chloroplastic; Involved in strigolactones biosynthesis by catalyzing the isomerization of the C9-C10 double bond in all-trans-beta- carotene leading to 9-cis-beta-carotene and providing the substrate for CCD7. Strigolactones are hormones that inhibit tillering and shoot branching through the MAX-dependent pathway, contribute to the regulation of shoot architectural response to phosphate-limiting conditions and function as rhizosphere signal that stimulates hyphal branching of arbuscular mycorrhizal fungi and trigger seed germination of root parasitic weeds (264 aa)
     
 
  0.921
CRTISO
Prolycopene isomerase, chloroplastic; Carotene cis-trans-isomerase that converts 7,9,9’-tri- cis-neurosporene to 9’-cis-neurosporene and 7,9,9’,7’-tetra-cis- lycopene (also known as prolycopene) into all-trans-lycopene. Isomerization requires redox-active components, suggesting that isomerization is achieved by a reversible redox reaction acting at specific double bonds. Isomerizes adjacent cis-double bonds at C7 and C9 pairwise into the trans-configuration, but is incapable of isomerizing single cis-double bonds at C9 and C9’. Carotenoid biosynthesis is partly required to form the pro [...] (595 aa)
