Enzyme activities of the MalQ and GlgP proteins

Purified MalQ (ZF32) protein
Substrate	Maltose	Maltotriose	Maltodextrin	Amylodextrin
Glucose-releasing activities	88.7±27.1*	62.8±6.4	17.4±2.7	≈0 (IU)
Purified GlgP (ZF27) protein
Phosphorylase activities	≈0	≈0	8.26±0.93	8.51±0.41 (IU)

^*In order for absorbance changes (ΔA) at 340 nm to be 0.1–0.4, the volumes of aliquots from reaction mixtures to assay mixtures were adjusted. When ΔA was <0.02, it was regarded as no activity (≈0). Mean±SD with duplicated three independent experiments are given.
