- bace1(β-site app cleaving enzyme),即β-分泌酶,是淀粉样前体蛋白(amyloid precursor protein,app)产生aβ的关键酶。bace1属于ⅰ型跨膜蛋白,由501个氨基酸组成,其中46~460位氨基酸为功能活性区域。bace1通过水解app670met-671asp之间的肽键,生成670个氨基酸的可溶性n末端和包含完整aβ区的app跨膜c端。后者经γ分泌酶进一步酶切形成aβ。最近的研究表明,bace1基因敲除小鼠脑内的aβ水平可降低90%,且其生理表型基本正常,显示了bace1抑制剂在ad治疗中的广阔前景[1]。通过酵母或昆虫表达系统表达活性bace1在最近已见报道[2,3]。然而,由于上述系统表达的蛋白量低,且纯化流程复杂,不适合bace1抑制剂的大规模筛选。而bace1的原核表达可克服以上缺陷,为筛选特异性抑制剂及研究bace1结构与功能关系提供大量材料,为最终从根本上治疗ad带来希望。
