富硒螺旋藻中含硒藻蓝蛋白的纯化、结晶及初步晶体学研究

从富硒螺旋藻中提取含硒藻蓝蛋白,经凝胶色谱和离子交换色谱纯化,应用悬滴气相扩散法,采用(NH4)2SO4和PEG4000作沉淀剂,获得了该蛋白质晶体的两种晶型.晶型Ⅰ属于单斜晶系,晶胞参数a=10.80 nm,b=11.70 nm,c=18.40 nm,β=90.2°,晶体空间群属于P21.单位晶胞中每个晶体学不对称单位含12个(αβ)单体,晶体衍射的最高分辨率达0.28 nm.晶型Ⅱ为六方晶系,晶胞参数为a=b=15.5 nm,c=4.03 nm,晶体空间群属于P63.晶体衍射的最高分辨率达0.28 nm.单位晶胞中每个晶体学不对称单位含1个(αβ)单体.对分子在晶体中的可能堆积方式进行了讨论.

Methionine sulfoxide reductases: selenoprotein forms and roles in antioxidant protein repair in mammals.

Full Abstract
Msrs (methionine sulfoxide reductases), MsrA and MsrB, are repair enzymes that reduce methionine sulfoxide residues in oxidatively damaged proteins to methionine residues in a stereospecific manner. These enzymes protect cells from oxidative stress and have been implicated in delaying the aging process and progression of neurodegenerative diseases. In recent years, significant efforts have been made to explore the catalytic properties and physiological functions of these enzymes. In the current review, we present recent progress in this area, with the focus on mammalian MsrA and MsrBs including their roles in disease, evolution and function of selenoprotein forms of MsrA and MsrB, and the biochemistry of these enzymes.
