STRINGSTRING
PORC protein (Arabidopsis thaliana) - STRING interaction network
"PORC" - Protochlorophyllide reductase C 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

PORCProtochlorophyllide reductase C; Phototransformation of protochlorophyllide (Pchlide) to chlorophyllide (Chlide) (401 aa)    
Predicted Functional Partners:
PCB2
PALE-GREEN AND CHLOROPHYLL B REDUCED 2; Catalyzes the conversion of divinyl chlorophyllide to monovinyl chlorophyllide. Reduces the 8-vinyl group of the tetrapyrrole to an ethyl group using NADPH as the reductant. The best substrate is (3,8-divinyl)-chlorophyllide a (DV-Chlidea). Very low activity with (3,8-divinyl)-protochlorophyllide a (DV- Pchlidea) and (3,8-divinyl)-magnesium-protoporphyrin IX monomethyl ester (DV-MPE). No activity with (3,8-divinyl)-chlorophyllide b (DV-Chlideb), (3,8-divinyl)-magnesium-protoporphyrin IX (DV-Mg- Proto) and either (3,8-divinyl)-chlorophyll a (DV-Ch [...] (417 aa)
   
 
  0.994
G4
Chlorophyll synthase; Involved in one of the last steps of the biosynthesis of chlorophyll a. Catalyzes the esterification of chlorophillide a or b with a preference for geranylgeranyldiphosphate (GGPP) rather than for phytyldiphosphate (PhyPP) (387 aa)
   
 
  0.980
CRD1
COPPER RESPONSE DEFECT 1; Catalyzes the formation of the isocyclic ring in chlorophyll biosynthesis. Mediates the cyclase reaction, which results in the formation of divinylprotochlorophyllide (Pchlide) characteristic of all chlorophylls from magnesium-protoporphyrin IX 13-monomethyl ester (MgPMME) (409 aa)
     
 
  0.978
CH1
CHLORINA 1; Catalyzes a two-step oxygenase reaction involved in the synthesis of chlorophyll b. Acts specifically on the non- esterified chlorophyllide a and not on chlorophyll a (536 aa)
   
 
  0.965
POR
PORCINO; Essential tubulin-folding protein involved in the final step of the tubulin folding pathway. Required for continuous microtubule cytoskeleton organization, mitotic division, cytokinesis, and to couple cell cycle progression to cell division in embryos and endosperms. Not essential for cell viability. Binds probably to the multimeric supercomplex, stimulating GTP hydrolysis by the bound beta-tubulin and the release of the alpha-/beta-tubulin heterodimer (345 aa)
           
  0.955
CLH1
Chlorophyllase 1; Catalyzes the hydrolysis of ester bond in chlorophyll to yield chlorophyllide and phytol. Shows a preferential activity toward chlorophyll a (324 aa)
     
 
  0.943
Tic62
NAD(P)-binding Rossmann-fold superfamily protein; Involved in protein precursor import into chloroplasts. Part of the redox regulon consisting of TIC32, TIC 55 and TIC62. Acts as a membrane anchor of LFNR1 and LFNR2. Has a NADPH- dependent dehydrogenase activity, but only after preincubation with lipids (By similarity) (641 aa)
   
 
  0.913
CLH2
Chlorophyllase 2; Catalyzes the hydrolysis of ester bond in chlorophyll to yield chlorophyllide and phytol (318 aa)
         
  0.912
CHLI1
Magnesium-chelatase subunit chlI; Involved in chlorophyll biosynthesis. Catalyzes the insertion of magnesium ion into protoporphyrin IX to yield Mg- protoporphyrin IX. The magnesium-chelatase is a complex of three subunits, CHLI, CHLD and CHLH. The reaction takes place in two steps, with an ATP-dependent activation followed by an ATP- dependent chelation step. Possesses high affinity for ATP and may play a major role in chlorophyll biosynthesis. Does not bind abscisic acid (ABA), but is a positive regulator of ABA signaling (424 aa)
     
   
  0.905
PORB
Protochlorophyllide reductase B; Phototransformation of protochlorophyllide (Pchlide) to chlorophyllide (Chlide) (401 aa)
   
0.900
