2-mercaptoethanol

Priestia megaterium

-

reducing agents in optimal concentrations of 20 mM or above are a prerequisite for high CO2 fixation turnovers, with dithiothreitol enhancing the carboxylation 16.2fold compared with a control without reducing agent, followed by ascorbate (15.5fold), Na2S2O5 (13.6fold) and 2-mercaptoethanol (7.2fold)

acetate

Priestia megaterium

-

if a carboxylic acid, such as acetate, is omitted from the reaction using the pure enzyme, no enzyme activity is found. As soon as a carboxylic acid is added, the decarboxylation starts immediately. The enzyme activity is increased with the number of carbon atoms, rising from formate to butyrate. Above four carbon atoms, the activity decreases. Pimelate, butyrate and propionate are the strongest activators
