Table 4.

Kinetic constants for MTS metabolism at pH 9.5 by Fmo1 and Fmo2.

Isoform	K_m^a	k_cat^b	k_cat/K_m
Fmo1	3.6 (2.3)^c	176 (57)	56.1 (19.7)
Fmo2	10.2 (2.5)	75 (22)	7.5 (0.4)

The K_m is in micromolar units.

The reported k_cat was calculated as nmoles MTSO formed min^-1 nmol^-1 FMO.

Mean and (S.D.) from analysis of two independently expressed batches of protein.
