STRINGSTRING
ALB1 protein (Arabidopsis thaliana) - STRING interaction network
"ALB1" - ALBINA 1 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

ALB1ALBINA 1; 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. Does not bind abscisic acid (760 aa)    
Predicted Functional Partners:
CHLM
Magnesium-protoporphyrin IX methyltransferase; Converts Mg-protoporphyrin IX to Mg-protoporphyrin IX methylester using S-adenosyl-L-methionine as a cofactor. Involved in chloroplast-to-nucleus signaling by acting as a negative effector of nuclear photosynthetic gene expression (312 aa)

GUN5
GENOMES UNCOUPLED 5; Multifunctional protein involved in chlorophyll synthesis, plastid-to-nucleus retrograde signaling and abscisic acid (ABA) perception. In chlorophyll synthesis, catalyzes the insertion of magnesium ion into protoporphyrin IX to yield Mg- protoporphyrin IX. The reaction takes place in two steps, with an ATP-dependent activation followed by an ATP-dependent chelation step. In addition to its function in the Mg-chelatase enzyme, is required for the plastid-to-nucleus retrogade signaling. The plastid-to-nucleus signal plays an important role in the coordinated expressi [...] (1381 aa)

PPOP1
Protoporphyrinogen oxidase; Catalyzes the 6-electron oxidation of protoporphyrinogen-IX to form protoporphyrin-IX (537 aa)
   
 
  0.995
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)
 
0.995
CHLI2
Magnesium chelatase i2; Involved in chlorophyll biosynthesis. Catalyzes the insertion of magnesium ion into protoporphyrin IX to yield Mg- protoporphyrin IX. The reaction takes place in two steps, with an ATP-dependent activation followed by an ATP-dependent chelation step. Possesses low affinity for ATP and may play a limited role in chlorophyll biosynthesis, and contributes to the assembly of the Mg-chelatase complex (418 aa)
 
0.992
HEMG2
Protoporphyrinogen oxidase; Catalyzes the 6-electron oxidation of protoporphyrinogen-IX to form protoporphyrin-IX (508 aa)
   
 
  0.989
HEM15
Ferrochelatase 1; Catalyzes the ferrous insertion into protoporphyrin IX. May have a role in dealing with oxidative stress. May be involved in wound-induced supply of heme to defensive hemoproteins outside plastids (466 aa)
   
 
  0.973
T9D9.1
Ferrochelatase 2; Catalyzes the ferrous insertion into protoporphyrin IX. May have a role in dealing with oxidative stress (522 aa)
   
 
  0.970
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)
 
   
  0.946
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)
