In such studies yeasts usually have the advantage that the level of the sulfonium
compound is high, and that it is accumulated in the vacuole. When 5'-
methylthioadenosine was incorporated into the culture medium, a significant
increase in the ...
The enzyme which catalyzes the transfer of the methyl group from S-
adenosylmethionine to guanidinoacetate was able to utilize almost all the
enzymically formed sulfonium compound, but only half the chemically
synthesized material.
