Participants

Reaction Conditions

Reaction Steps

A reaction mixture comprising 3-cyanopyridine 20 (0.1-1.0 M; 1.0-1.8 ml), aqueous NaCl solution (0.85% (w/v); 0.7 to 0.1 ml), potassium phosphate buffer (0.1 M; pH 7.0; 0.3 ml) and cell suspension (0.01 ml) was incubated with shaking at 30° C. for 10 min. The total volume of the reaction mixture was between 2.0 to 2.2 ml, depending on the 3-cyanopyridine concentration. The reaction was stopped by adding HC1(2 M; 0.1 ml). After centrifugation of the reaction mixture (12 000 rpm; 5 min), the amount of nicotinamide produced was determined by means of HPLC according to Example 1. The KM value determined was 160 mM (FIG. 10).
