2.4.1.100	2,1-fructan:2,1-fructan 1-fructosyltransferase	spear	green spear. Activity of 2,1-fructan:2,1-fructan 1-fructosyltransferase is high in the top portion and decreases during storage, while in the middle and bottom portions, its activity varies slightly. The ratio of 6G-fructosyltransferase and 2,1-fructan:2,1-fructan 1-fructosyltransferase is independent of temperature	-, 687335	
2.4.1.243	6G-fructosyltransferase	spear	-	687335	
2.4.1.99	sucrose:sucrose fructosyltransferase	spear	green spear. During storage, activity of sucrose:sucrose fructosyltransferase does not vary in the bottom portion but initially increase in the middle and top portions	-, 687335	
3.5.1.1	asparaginase	spear	activity in all tested varieties is significantly higher in roots than in spears and leaves	710773	
4.4.1.14	1-aminocyclopropane-1-carboxylate synthase	spear	ACC synthase is rapidly induced in excised top portions but no significant ACC synthase activity is observed in excised bottom portions. In top portions, ACC synthase reaches a peak 8 h after harvest and thereafter starts to decline	665124
