We previously reported that the absorption spectrum at low temperatures of iodinated bacteriorhodopsin can be separated into four components with maxima at shorter wavelengths than in native bacteriorhodopsin. In this study, the time course of the formation of each spectral component after iodination was analyzed, revealing that these four components correspond to four different iodinated states of tyrosine residues interacting with the retinal chromophore of bacteriorhodopsin. Therefore at least two tyrosine residues interact with the chromophore of bacteriorhodopsin.
我们之前报道过，碘化细菌视紫红质在低温下的吸收光谱可分为四个组分，其最大值出现在比天然细菌视紫红质更短的波长处。在本研究中，分析了碘化后各光谱组分形成的时间进程，结果表明这四个组分对应于与细菌视紫红质的视黄醛发色团相互作用的酪氨酸残基的四种不同碘化状态。因此，至少有两个酪氨酸残基与细菌视紫红质的发色团相互作用。
