Abstract

The quenching by radiationless energy transfer of the ultraviolet fluorescence of Tyr-99 and Tyr-138 by bound 1-anilinonaphthalene-8-sulfonate (1,8-ANS) has been employed to determine the separation of a hydrophobic binding site of 1,8-ANS from each of the tyrosines. The results suggest that the dominant binding site is located in the N-terminal region of domain III.

摘要

通过结合的1-苯胺基萘-8-磺酸盐（1,8-ANS）对Tyr-99和Tyr-138的紫外荧光进行无辐射能量转移猝灭，已用于确定1,8-ANS的疏水结合位点与每个酪氨酸之间的距离。结果表明，主要结合位点位于结构域III的N端区域。
