Methionine synthesis from 5-methylthioribose in apple tissue

The primary fate of 5-methylthioribose in apple tissue is the formation of methionine. Using dual labeled 5-methylthioribose, it was shown that both the CH 3S- group and the ribose portion of 5-methylthioribose were equally incorporated into methionine. Thus, the pathway involves modification of the...

Summary:The primary fate of 5-methylthioribose in apple tissue is the formation of methionine. Using dual labeled 5-methylthioribose, it was shown that both the CH 3S- group and the ribose portion of 5-methylthioribose were equally incorporated into methionine. Thus, the pathway involves modification of the ribose portion of 5-methylthioribose into the 2-aminobutyrate portion of methionine. This pathway functions to recycle methionine for continued synthesis of ethylene in fruit tissues. The methionine cycle in relation to ethylene biosynthesis is presented.
