ID   2.1.1.262
DE   squalene methyltransferase.
CA   squalene + 2 S-adenosyl-L-methionine = 3,22-dimethyl-1,2,23,24-
CA   tetradehydro-2,3,22,23-tetrahydrosqualene + 2 S-adenosyl-L-homocysteine +
CA   2 H(+).
CC   -!- Two isoforms differing in their specificity were isolated from the
CC       green alga Botryococcus braunii BOT22.
CC   -!- TMT-1 gave more of the dimethylated form whereas TMT2 gave more of
CC       the monomethylated form.
