L-Methionine induced production of ethylene by Saccharomyces cerevisiae growing in lactate medium. The production induced by L-methionine was inhibited by pyruvate, and elevated by glucose. Labeled ethylene was produced when L-[U-14C]methionine, but not [U-14C]glucose, was fed to the yeast. The mutant S. cerevisiae G1332 (ade-, met-) did not produce significant amounts of ethylene unless L-methionine was added. Thus L-methionine acts as a precursor of ethylene in S. cerevisiae. The role of glucose appears to be other than as a precursor.
L-甲硫氨酸诱导在乳酸培养基中生长的酿酒酵母产生乙烯。L-甲硫氨酸诱导产生的乙烯受到丙酮酸的抑制，并因葡萄糖而增加。当向酵母投喂L-[U-¹⁴C]甲硫氨酸而非[U-¹⁴C]葡萄糖时，会产生标记的乙烯。酿酒酵母突变体G1332（腺嘌呤缺陷型、甲硫氨酸缺陷型）除非添加L-甲硫氨酸，否则不会产生大量乙烯。因此，L-甲硫氨酸在酿酒酵母中作为乙烯的前体起作用。葡萄糖的作用似乎并非作为前体。
