fkbO

Gene
fkbO
Protein
Chorismatase
Organism
Streptomyces hygroscopicus
Length
344 amino acids
Function
Involved in the biosynthesis of the macrocyclic amino acid-linked polyketides FK506 and FK520 which are potent immunosuppressants that prevent T-cell proliferation through initial binding to the immunophilin FKBP12. Catalyzes the hydrolysis of chorismate via a 1,4-conjugate elimination of water to yield (4R,5R)-4,5-dihydroxycyclohexa-1,5-dienecarboxylic acid (DCDC).
Similarity
Belongs to the FkbO/Hyg5 family.
Mass
