| | CA Inhibition Assay |
| Description: | An Applied Photophysics stopped-flow instrument has been used for assaying the CA-catalyzed CO2 hydration activity. Phenol red has been used as indicator, working at the absorbance maximum of 557 nm. The inhibition constants were obtained by nonlinear least-squares methods. The IC50 was obtained by using curve-fitting algorithm, and Ki values were calculated by using the Cheng-Prusoff equation. The catalytic activity of these enzymes was calculated from Lineweaver-Burk plots, and represent the mean from at least three different determinations. |
