Description

The mechanism of thiomethyladenosine accumulation in yeast was studied by attempting to substitute homocysteine methylmercaptane methylmercaptoethanol and methylome captopropionaldehyde for methionine as a specific precursor. Negative results militate against transmethylation as the underlying mechanism. Tracer studies with methyl-C14- and and S35-labeled methionine suggest transthiomethylation with intermediate formation of a thetin-like compound tentatively termed methionyladenosine. The occurrence of another S-containing compound of this class, probably homo-cysteinyladenosine, is indicated. It appears that thiomethyl- adenosine is a split product of methionyladenosine
