Abstract
Reversible binding of the tetrahedral oxoanions MoO(4)(2-) and WO(4)(2-) to two carboxylato ligands of the soluble scavenger protein WtpA from the hyperthermophilic archaeon Pyrococcus furiosus enforces a quasi-octahedral MO(6) coordination in which the +VI oxidation state is destabilized.
摘要
四面体含氧阴离子 MoO(4)(2-) 和 WO(4)(2-) 与来自嗜热古菌 Pyrococcus furiosus 的可溶性清除蛋白 WtpA 的两个羧基配体的可逆结合强制形成准八面体 MO(6) 配位，其中 +VI 氧化态被削弱。
