perfluorobenzoarylsulfonamide ligands bind to human carbonic anhydrase with a conserved binding geometry, an enthalpy‐driven binding, and indistinguishable binding affinities (see picture). These data support the pervasive theory that the lock‐and‐key model disregards an important component of binding: the water, which fills the binding pocket of the protein and surrounds the ligand.
重要的是水。成对的苯并和全氟苯甲酰基磺酰胺配体以保守的结合几何结构,焓驱动结合和难以区分的结合亲和力与人碳酸酐酶结合(参见图片)。这些数据支持普遍的理论,即锁匙模型忽略了结合的重要组成部分:水充满了蛋白质的结合口袋并包围了配体。
