Metabolic studies on 5'-methylthioxylofuranosyl adenine, a natural analog of 5'-methylthioadenosine.

Xylosyl-MTA, an analog of MTA, is a secondary metabolite of the marine mollusc Doris verrucosa. Biochemical studies conducted to evaluate the effect of this compound on the enzymes involved in MTA metabolism have demonstrated that it does not interfere with MTA catabolism and with its regulatory effects on polyamine biosynthesis.
