Muscle glycogen content, GBE and GS activity

	Glycogen content w/w	GBE activity (nmol/min/mg)	GS activity (nmol/min/mg)
			Without G6P	With G6P
Gbe1−/−	0.8 ± 1.6*	0 ± 2*	26 ± 1.8*	44 ± 1.0*
Gbe1+/−	13.1 ± 3.13	153 ± 17	17 ± 3.2	68 ± 3.1
Gbe1+/+	10.5 ± 1.5	227 ± 44	19 ± 1.0	69 ± 1.4

Values represent the Mean ± SD, *P < 0.01 Gbe1^−/− (n = 5) versus both Gbe1^−/+ (n = 4) and Gbe1^+/+(n = 5).
