Kinetic Parameters of Substrate Activation

Enzyme	Amino or Aryl Acid	K_m^a	V_max^a
EntE	2,3-Dhb	2.9 ± 0.4	3168.2 ± 151.2
EntE+YbdZ	2,3-Dhb	1.9 ± 0.5	1164.2 ± 75.8
EntF^b	L-Ser	7162.1 ± 413.5, 4589.5 ± 313.0	678.3 ± 13.1, 1342.2 ± 27.3
EntF+YbdZ^b	L-Ser	655.9 ± 53.0, 240.1 ± 46.7	442.2 ± 11.7, 1066.5 ± 53.5

K_m is in μM, V_max is in pmol prod./min/μg protein.

The kinetic parameters for two different preparations are presented.
