Effective Photoinactivation of Alpha-Amylase, Catalase and Urease at 222 nm Emitted by an KrCI- Excimer Lamp.

The article discusses the effectiveness of photoinactivation of alpha-amylase, catalase, and urease that were irradiated with 222 nm radiation emitted by a KrCl-excimer lamp. Before and after irradiation, the relative activities were calculated. SDS-PAGE analysis was used in assessing the degradation caused by UV-radiation. Results showed that inactivation of the proteins is effective with the 222 nm excimer lamp wherein the irradiation with the excimer lamp can reduce the relative activities of amylase and urease to 15% and catalase to 60%.
