Abstract
ADP-Glucose pyrophosphorylase activity has been detected in relatively low amounts in the embryos and endosperms of sh(2) and bt(2) mutant maize seeds. The total enzyme activities in sh(2) and bt(2) were about 12% and 17% respectively, of that found in starchy maize seeds (Dekalb 805). The ADP-glucose pyrophosphorylases from the starchy and mutant maize seeds were activated by 3-phosphoglycerate. However, the extent of the activation of the sh(2) enzyme was not as great as that observed with the bt(2) and Dekalb 805 enzymes. The low levels of ADP-glucose pyrophosphorylase activity in the maize mutants correlate well with the low levels of starch found in the endosperm of these mutants.
摘要
ADP-葡萄糖焦磷酸化酶活性在 sh(2)和 bt(2)突变体玉米种子的胚胎和胚乳中被检测到的含量相对较低。sh(2)和 bt(2)中的总酶活性分别约为 starchy 玉米种子(Dekalb 805)中发现的酶活性的 12%和 17%。淀粉质和突变体玉米种子的 ADP-葡萄糖焦磷酸化酶被 3-磷酸甘油酸激活。然而，sh(2)酶的激活程度不如 bt(2)和 Dekalb 805 酶观察到的那么大。玉米突变体中 ADP-葡萄糖焦磷酸化酶活性水平较低，与这些突变体胚乳中发现的淀粉含量较低密切相关。
