研究者用配体感知的 de novo 蛋白设计,为三种 Janelia Fluor 染料造出小型、纳摩尔亲和力且彼此正交的 NovoTag,并把蛋白口袋进一步改造成寿命调节器、共价标签和染料诱导二聚系统。
Ligand-aware de novo protein design produced compact, nanomolar-affinity and mutually orthogonal NovoTags for three Janelia Fluor dyes, then turned their binding pockets into lifetime modulators, a covalent tag and a dye-induced dimerization system.
