Kinetic parameters of the acetate kinase from intestinal sulfate-reducing bacteria.

Kinetic parameters	Sulfate-reducing bacteria
	Desulfovibrio piger Vib-7	Desulfomicrobium sp. Rod-9
V0 (µmol × min-1 × mg-1 protein)	6.16 ± 0.63	1.39 ± 0.14***
Pmax (µmol × mg-1 protein)	20.48 ± 2.51	6.74 ± 0.68***
τ  (min)	3.33 ± 0.34	4.82 ± 0.49

Comment: V0 is initial (instantaneous) reaction velocity; Pmax is maximum amount (plateau) of the product of reaction; is the reaction time (half saturation period). Statistical significance of the values M ± m, n = 5; ***P<0.001, compared to the D. piger Vib-7 strain.
