Diadenosine 5',5'''-p1,p4-tetraphosphate (Ap4A) alpha, beta-phosphorylase from yeast Saccharomyces cerevisiae catalyzes two reactions: Ap4A cleavage and nucleoside diphosphate--phosphate (NDP-Pi) exchange. In both reactions phosphate can be substituted by arsenate, chromate, molybdate, tungstate or vanadate. In the presence of each anion, nucleoside 5'-monophosphate (NMP) always accumulates as a product of the reaction. This indicates that an unstable NMP anion is formed as an intermediate.
来自酿酒酵母的二腺苷5',5'''-p1,p4-四磷酸（Ap4A）α,β-磷酸化酶催化两个反应：Ap4A裂解和核苷二磷酸-磷酸（NDP-Pi）交换。在这两个反应中，磷酸盐均可被砷酸盐、铬酸盐、钼酸盐、钨酸盐或钒酸盐取代。在每种阴离子存在的情况下，核苷5'-单磷酸（NMP）总是作为反应产物积累。这表明形成了一种不稳定的NMP阴离子作为中间体。
