Methyl transfer reaction
WebHowever, other methyl-transfer reactions using SMM as the methyl donor are still speculative (Giovanelli et al., 1980). SMM is believed to function as a storage form for … WebIn this work, we show that the ethyl and methyl esters of (S)-mandelic acid are substrates for MDH. Although the binding affinity of the neutral esters is 25-50-fold lower relative to the negatively charged (S)-mandelate, they are oxidized with comparable k (cat)s.
