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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
ABC1Protein ABC transporter 1, mitochondrial; Atypical kinase involved in the biosynthesis of coenzyme Q, also named ubiquinone, an essential lipid-soluble electron transporter for aerobic cellular respiration; Belongs to the protein kinase superfamily. ADCK protein kinase family. (623 aa)
CYP89A9Cytochrome P450 89A9; Involved in the chlorophyll breakdown by its action in nonpolar fluorescent chlorophyll catabolite (FCC) decarbonylation. (511 aa)
THF1Protein THYLAKOID FORMATION 1, chloroplastic; Involved in a dynamic process of vesicle-mediated thylakoid membrane biogenesis. Required for the normal organization of vesicles into mature thylakoid stacks and ultimately for leaf development. Also involved in a sugar-signaling mechanism in roots by mediating signaling between the plasma membrane and the plastid. Probably acts downstream of the plasma membrane-delimited heterotrimeric G-protein GPA1 in a D- glucose signaling pathway; Belongs to the THF1 family. (300 aa)
CLH2Chlorophyllase-2, chloroplastic; Catalyzes the hydrolysis of ester bond in chlorophyll to yield chlorophyllide and phytol. (318 aa)
ETFBElectron transfer flavoprotein subunit beta, mitochondrial; The electron transfer flavoprotein serves as a specific electron acceptor for several dehydrogenases, including five acyl-CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase. It transfers the electrons to the main mitochondrial respiratory chain via ETF- ubiquinone oxidoreductase (ETF dehydrogenase) (By similarity). Involved in leucine catabolism and in phytol degradation. (251 aa)
PAOPheophorbide a oxygenase, chloroplastic; Catalyzes the key reaction of chlorophyll catabolism, porphyrin macrocycle cleavage of pheophorbide a (pheide a) to a primary fluorescent catabolite (pFCC). Works in a two-step reaction with red chlorophyll catabolite reductase (RCCR). Creates the intermediate RCC through the opening of the porphyrin macrocycle by the introduction of one atom of molecular oxygen at the alpha-methine bridge. Seems to be specific for pheide a. Belongs to the chlorophyll catabolic enzymes (CCEs). (537 aa)
PPHPheophytinase, chloroplastic; Alpha/beta hydrolase dephytylating specifically the Mg-free chlorophyll pigment (pheophytin), yielding pheophorbide. No activity on chlorophyll. Belongs to the chlorophyll catabolic enzymes (CCEs). (484 aa)
SGRLMagnesium dechelatase SGRL, chloroplastic; Magnesium chelatase involved in chlorophyll a degradation in the chlorophyll-protein complexes of photosystem I (PSI) and photosystem II (PSII). Contributes to the degradation of PSI and PSII in the thylakoid membranes. Recombinant SGRL possesses high dechelating activity against chlorophyllide a, very low activity against chlorophyll a, and no activity against chlorophyll b. Contributes to abiotic stress-induced chlorophyll degradation and leaf yellowing during vegetative plant growth. Belongs to the staygreen family. (260 aa)
NYC1Probable chlorophyll(ide) b reductase NYC1, chloroplastic; Involved in chlorophyll b degradation. Belongs to the chlorophyll catabolic enzymes (CCEs); Belongs to the short-chain dehydrogenases/reductases (SDR) family. (496 aa)
ABC1K1Protein ACTIVITY OF BC1 COMPLEX KINASE 1, chloroplastic; Kinase that can phosphorylate the tocopherol cyclase VTE1, a key enzyme of tocopherol (vitamin E) metabolism and involved in the recycling of oxidated alpha-tocopherol quinone, possibly stabilizing it at plastoglobules. Regulates also plastoglobule protein composition. Prevents photodamage of chloroplasts under continuous red light, thus working in opposition to ABC1K3. Together with ABC1K1, contributes to plastoglobule (PG) function in prenyl-lipid metabolism, stress response, and thylakoid remodeling. Involved in chlorophyll de [...] (682 aa)
NOLChlorophyll(ide) b reductase NOL, chloroplastic; Required for chlorophyll b degradation. Chlorophyll b, chlorophyllide b, pheophorbide b and pheophytin b can be used as substrates. Belongs to the chlorophyll catabolic enzymes (CCEs). Belongs to the short-chain dehydrogenases/reductases (SDR) family. (348 aa)
RCCRRed chlorophyll catabolite reductase, chloroplastic; Catalyzes the key reaction of chlorophyll catabolism, porphyrin macrocycle cleavage of pheophorbide a (pheide a) to a primary fluorescent catabolite (pFCC). Works in a two-step reaction with pheophorbide a oxygenase (PaO) by reducing the C20/C1 double bond of the intermediate, RCC. Belongs to the chlorophyll catabolic enzymes (CCEs). (319 aa)
SGR2Magnesium dechelatase SGR2, chloroplastic; Magnesium chelatase involved in chlorophyll a degradation in the chlorophyll-protein complexes of photosystem I (PSI) and photosystem II (PSII).
