Abstract

Investigations comparing tryptophan fluorescence of mitochondrial actin-like protein with that of skeletal and smooth muscle actins have shown that the mitochondrial protein is characterized by a fluorescence spectrum peak at a longer wavelength (337 nm), by a certain broadening of this peak (56 nm) and by a reduction in the lifespan of the excited state of tryptophanyls (2.7 ns). The data obtained suggest the existence of peculiarities in the structure of mitochondrial actin-like protein.

摘要

将线粒体肌动蛋白样蛋白的色氨酸荧光与骨骼肌和平滑肌肌动蛋白的色氨酸荧光进行比较的研究表明,线粒体蛋白的特征在于在更长波长(337nm)处有一个荧光光谱峰,该峰有一定程度的展宽(56nm),并且色氨酸残基激发态的寿命缩短(2.7纳秒)。所获得的数据表明线粒体肌动蛋白样蛋白的结构存在特殊性。
