CYT1

Gene
CYT1
Protein
Mannose-1-phosphate guanylyltransferase 1
Organism
Arabidopsis thaliana
Length
361 amino acids
Function
Catalyzes a reaction of the Smirnoff-Wheeler pathway, the major route to ascorbate biosynthesis in plants. Plays an essential role in plant growth and development and cell-wall architecture. Provides GDP-mannose, used for cell wall carbohydrate biosynthesis, protein N-glycosylation, as well as for the biosynthesis of the antioxidant ascorbate.
Similarity
Belongs to the transferase hexapeptide repeat family.

Gene
CYT1
Protein
Cytochrome c1, heme protein, mitochondrial
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Length
309 amino acids
Function
Heme-containing component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain that generates an electrochemical potential coupled to ATP synthesis. The complex couples electron transfer from ubiquinol to cytochrome c.
Similarity
Belongs to the cytochrome c family.
