pH
Organism pH Range Comment Methanocaldococcus jannaschii 6.5 - 10 no activity is detected at pH 6.5 and the measured activity steadily increases to pH 10.0. Higher pH values are tested but the observation of activity is dependent on the buffer used and are not reported here. Agmatine shows no hydrolysis in the pH 10 and 11 buffers and assay conditions used Pyrococcus horikoshii 9.5 - 12.5 pH 9.5: about 50% of maximal activity, pH 12.5: about 85% of maximal activity
