Figure 1 CBS activities measured in an E. coli expression system. Mutations were introduced as described in the Patients, Material, and Methods section. Bacterial lysates were assayed for CBS activity, and the mean CBS activity of a control construct (40.3 nmol cystathionine formed/mg protein/h) has been set to 100%. Each bar represents another mutated construct and is the mean of two independently performed CBS assays.
