Biochemical characterization of the purified recombinant AmCDase.

Abstract

<p>Hydrolysis of D-erythro-C12-NBD-ceramide was measured by the method described in the “Materials and Methods”. The purified recombinant AmCDase was used for enzyme activity detection, and the reaction continued for 1 h. Values are the means ± SD of three replicates from each independent experiment. (a) Michaelis–Menten represented AmCDase activity by increasing concentrations of D-erythro-C12-NBD-ceramide. (b) Lineweaver-Burk plots for AmCDase. (c) Effects of different cations on AmCDase activity. (d) pH optimum of AmCDase. The buffers were used as described in the experimental procedures.</p
