Botryococcene C-methyltransferase

Template:Infobox enzyme Botryococcene C-methyltransferase (Template:EC number, TMT-3) is an enzyme with systematic name S-adenosyl-L-methionine:botryococcene C-methyltransferase.

Function

This enzyme catalyses the following chemical reaction:

2 S-adenosyl-L-methionine + C30 botryococcene $\rightleftharpoons$ 2 S-adenosyl-L-homocysteine + 3,20-dimethyl-1,2,21,22-tetradehydro-2,3,20,21-tetrahydrobotryococcene (overall reaction)

(1a) S-adenosyl-L-methionine + C30 botryococcene $\rightleftharpoons$ S-adenosyl-L-homocysteine + 3-methyl-1,2-didehydro-2,3-dihydrobotryococcene

(1b) S-adenosyl-L-methionine + 3-methyl-1,2-didehydro-2,3-dihydrobotryococcene $\rightleftharpoons$ S-adenosyl-L-homocysteine + 3,20-dimethyl-1,2,21,22-tetradehydro-2,3,20,21-tetrahydrobotryococcene

(2a) S-adenosyl-L-methionine + C30 botryococcene $\rightleftharpoons$ S-adenosyl-L-homocysteine + 20-methyl-21,22-didehydro-20,21-dihydrobotryococcene

(2b) S-adenosyl-L-methionine + 20-methyl-21,22-didehydro-20,21-dihydrobotryococcene $\rightleftharpoons$ S-adenosyl-L-homocysteine + 3,20-dimethyl-1,2,21,22-tetradehydro-2,3,20,21-tetrahydrobotryococcene

This enzyme is isolated from the green alga Botryococcus braunii BOT22.
