The presence of a previously unidentified plant enzyme, 5-methylthioribose kinase, has been demonstrated to exist in cell-free extracts from several fruit tissues. The enzyme catalyzes the ATP-dependent phosphorylation of 5-methylthioribose to 5-methylthioribose-1-phosphate. Enzyme activity has been found in avocado, pear, apple, strawberry and tomato tissues. The significance of the presence of this enzyme in relation to ethylene biosynthesis is discussed.
