Ultrafast Dynamics of KR2 Sodium Pump by 1ransari2342121 is a document available to read on EtoBox.

This study presents the first femtosecond time-resolved absorption analysis of the retinal protein KR2, a light-driven sodium-ion pump, revealing its ultrafast photoreaction dynamics. The findings indicate that the deactivation of the excited S1 state occurs in 180 fs, which is significantly faster than that of bacteriorhodopsin, leading to the formation of the J intermediate and subsequent conversion to the K intermediate. These insights enhance the understanding of the unique mechanisms underlying the sod
