亚洲玉米螟Ostrinia furnacalis是我国玉米最重要的害虫,了解亚洲玉米螟表皮形成的机制将有助于对其开展生物防治。表皮蛋白和几丁质是构成昆虫表皮的两种主要成分,因此研究两者的相互作用对于阐明昆虫表皮形成机制具有关键意义。CPR9是亚洲玉米螟体壁表皮转录组中相对丰度最高的表皮蛋白基因。序列分析发现CPR9属于CPR家族中RR-1亚家族的表皮蛋白,含有R&R结构域,可能是通过结合几丁质来发挥功能。为了研究CPR9与几丁质的相互作用,本研究利用p ET-SUMO载体实现了SUMO-CPR9融合蛋白的可溶表达,并通过SUMO蛋白酶处理及两次金属螯合亲和层析纯化了CPR9,平均收率为5 mg/L。几丁质结合试验发现,CPR9对不同类型的几丁质的结合具有选择性。CPR9对α-几丁质结合能力很强,对胶体几丁质结合能力较强,但不与β-几丁质结合。脱乙酰几丁质(壳聚糖)结合试验发现,CPR9能与脱乙酰几丁质结合并使其发生团聚。圆二色光谱分析表明,CPR9在结合脱乙酰几丁质后,其二级结构中平行β折叠和β转角比例上升,反平行β折叠及无规卷曲比例下降。本研究发现了CPR家族表皮蛋白与不同类型几丁质的结合存在特异性,而且在结合过程中会发生结构变化,有助于进一步了解昆虫表皮的形成机制。
