FIG. 6.

Proposed pathway of the initial biotransformation of CL-20 catalyzed by salicylate 1-monooxygenase followed by secondary decomposition. Nitrogen atoms shown in bold were actually ring- nitrogens and were uniformly labeled in [¹⁵N] CL-20. Secondary decomposition of intermediate III is shown; intermediate IV might also decompose like intermediate III. The intermediate shown in brackets was not detected.
