acts as a cofactor
-
induction of enzyme expression, erythroleukemia cells
-
significantly increase of enzyme activity and expression in human colon cancer cell line HT-29
-
highly activating for the wild-type enzyme
-
in pH-controlled cultures, the addition of 20 mM acetate promotes a more vigorous solventogenic fermentation
-
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
-
activation of mutant K202A
