免疫相关的蛋白设计有个先验经验,那就是设计出来的蛋白质需要有广谱性的结合能力,因此不能针对某些抗体或结合蛋白做过度的优化,比如第一个测试案例是幻想设计RSV病毒疫苗类似物,我们的目标是生成携带中和性抗体表位 (motif) 的de novo蛋白,通常只希望motif的部分能与抗体产生相互作用,否则体内产生的其他抗体会与设计的...
De novo protein design seeks to generate proteins with specified structural and/or functional properties, for example, making a binding interaction with a given target12, folding into a particular topology13or containing a catalytic site4. Denoising diffusion probabilistic models (DDPMs), a powerful ...

De novo蛋白质设计的概念和方法(上) 本文主要讨论在基于物理的建模方法和人工智能的交汇处,从头蛋白质设计领域的现状,可以De novo“写入”具有新形状和分子功能的蛋白质,而无需从自然界中发现的蛋白质开始。 背景 蛋白质可以将化学反应的速度加快许多数量级,将光的能量转化为化学能,并以维持生命所需的准确性和精确...
protein engineering as it could enable the construction of switchable nanomaterials, cooperatively activated biosensors and molecular machines that perform work by means of coordinated movements among their components. Previous work on the de novo design of allostery has demonstrated coupling between two ...
