TABLE 3.

Effects of enzyme inhibitors on the CL-20 biotransformation activity of a membrane-associated enzyme(s)c

Inhibitor (2 mM) % CL-20 biotransformation activitya
None (control) 100 ± 1.7
Diphenyliodonium 38 ± 2.3
Dicumarol 86 ± 3.5
Metyrapone 91 ± 2.8
Carbon monoxideb 87 ± 2.2
2,2-Dipyridyl 92 ± 3.4
a

One hundred percent CL-20 biotransformation activity was equivalent to 11.5 nmol h−1 mg of protein−1. Data are mean percentages of CL-20 biotransformation activity ± standard errors (n = 3).

b

Carbon monoxide was bubbled through the aqueous phase and headspace for 60 s in sealed vials.

c

The CL-20 biotransformation activity of the membrane-associated enzyme(s) (1 mg/ml) was determined at pH 7.0 and 30°C after 1 h under anaerobic conditions.
