The mass spectrum of imG-14 produced in the presence of protiated substrate in H2O (Inline graphic), deuterated substrate in H2O (Inline graphic), protiated substrate in D2O (Inline graphic), and deutertated substrate in D2O (Inline graphic). The peak due to deuterium incorporation is labeled. The natural abundance 13C peak is visible at m/z 323.1168.
