alteration in both secondary and tertiary structures cause enzyme deactivation in acidic pH, while increased deactivation rates at alkaline pH are attributed to the variation of tertiary structure over time. The secondary structure of enzyme DnXR is completely affected at pH 5.0 and is retained at pH 5.5 with altered signature. Negative ellipticity values are reduced at pH 6.0 and 10.0 without alteration in secondary signatures. Overlapping spectra are obtained at pH 7.0, pH 8.0, and pH 9.0 with the highest signals.
