the specific activities of acid and alkaline invertases ( beta-d-fructofuranoside fructohydrolase , ec 3.2.1.26 ) , sucrose synthase ( udpglucose : d-fructose 2-alpha-d-glucosyltransferase , ec 2.4.1.13 ) , hexokinase ( atp : d-hexose 6-phosphotransferase , ec 2.7.1.1 ) , and fructokinase ( atp : d-fructose 6-phosphotransferase , ec 2.7.1.4 ) were determined in soybean ( glycine max l. merr cv williams ) nodules at different stages of development and , for comparison , in roots of nonnodulated soybeans .
