Peroxiredoxins (Prxs) are a very large and highly conserved family of peroxidases that reduce peroxides, with a conserved cysteine residue, designated the "peroxidatic" Cys (CP) serving as the site of oxidation by peroxides (Hall et al., 2011; Rhee et al., 2012). Peroxides oxidize the CP-SH to cysteine sulfenic acid (CP-SOH), which then reacts with another cysteine residue, named the "resolving" Cys (CR) to form a disulfide that is subsequently reduced by an appropriate electron donor to complete a catalytic cycle. This overview summarizes the status of studies on Prxs and relates the following 10 minireviews.
过氧化物酶体增殖物激活受体(Prxs)是一个非常庞大且高度保守的过氧化物酶家族,可还原过氧化物,其具有一个保守的半胱氨酸残基,称为“过氧化物酶”半胱氨酸(CP),作为过氧化物氧化的位点(Hall等人,2011年;Rhee等人,2012年)。过氧化物将CP-SH氧化为半胱氨酸亚磺酸(CP-SOH),然后它与另一个半胱氨酸残基反应,称为“分解”半胱氨酸(CR),形成二硫键,随后由合适的电子供体将其还原以完成催化循环。本综述总结了关于Prxs的研究现状,并关联了以下10篇小型综述。
