AB - Abstract ADP-Glucose pyrophosphorylase activity has been detected in relatively low amounts in the embryos and endosperms of sh2 and bt2 mutant maize seeds. The total enzyme activities in sh2 and bt2 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 sh2 enzyme was not as great as that observed with the bt2 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. 2 Present address: Department of Horticulture, University of Illinois, Urbana, Illinois. 1 Supported by Grant AI 05520 from the Public Health Service and a fellowship from the National Science Foundation.
