title: Methanol production by Mycobacterium smegmatis.
abstract: Mycobacterium smegmatis cells produce [3H]methanol when incubated with [methyl-3H]methionine. The methanol is derived from S-adenosylmethionine rather than methyltetrahydrofolate. M. smegmatis cells carboxymethylate several proteins, and some of the methanol probably results from their demethylation, but most of the methanol may come from an unidentified component with a high gel mobility. Although methanol in the medium reached 19 microM, it was not incorporated into the methylated mannose polysaccharide, a lipid carrier in this organism.
