TABLE 2.

Kinetic parameters for the conversion of Glc-1P to Glc-6P by Sll0726 and Slr1334 in the presence of different effector molecules as indicated^a

Effector	Sll0726			Slr1334			Catalytic efficiency ratio (%) (Slr1334/Sll0726)
	Km (mM)	Kcat (s−1)	Kcat/Km (M−1s−1)	Km (mM)	Kcat (s−1)	Kcat/Km (M−1s−1)
No effector	3.27 ± 0.21	138 ± 3.7	42.2 × 103	3.31 ± 0.14	7.5 ± 0.1	2.3 × 103	5.5
Glc-1,6-BP	0.19 ± 0.04	415 ± 30.6	3038.9 × 103	0.09 ± 0.02	14.4 ± 0.7	158.1 × 103	5.2
Frc-1,6-BP	26.86 ± 3.35	218 ± 21.3	8.1 × 103	0.03 ± 0.01	3.6 ± 0.2	117.5 × 103	1,450

^a K_m and K_cat values are means of triplicates with ± SD. Catalytic efficiency ratio is given in percentage and was calculated by the ratio of K_cat/K_m of Slr1334 and Sll0726.
