HGGT

Gene

HGGT

Protein

Homogentisate geranylgeranyltransferase

Organism

Hordeum vulgare

Length

408 amino acids

Function

Involved in the synthesis of tocotrienol (vitamin E). Catalyzes the condensation of homogentisate and geranylgeranyl diphosphate to form 2-methyl-6-geranylgeranylbenzoquinol (PubMed:12897790, PubMed:21223386). Possesses low activity with phytyl diphosphate as substrate (PubMed:21223386).

Similarity

Belongs to the UbiA prenyltransferase family.

Gene

HGGT

Protein

Homogentisate geranylgeranyltransferase, chloroplastic

Organism

Oryza sativa subsp. japonica

Length

404 amino acids

Function

Involved in the synthesis of tocotrienol (vitamin E) (PubMed:21175184). Catalyzes the condensation of homogentisate and geranylgeranyl diphosphate to form 2-methyl-6-geranylgeranylbenzoquinol. Possesses low activity with phytyl diphosphate as substrate (By similarity). Tocotrienols functions to limit lipid peroxidation during seed germination (PubMed:21175184).

Similarity

Belongs to the UbiA prenyltransferase family.
