蛋白质设计的三种全局优化策略 蛋白质设计的物理原则(Physical principles that underlie protein design) 蛋白质折叠的驱动力是将疏水残基从溶剂中埋藏到蛋白质的核心部位(三种学说之一),为了最小化蛋白质在溶剂中占据的空穴和最小化原子重叠的范德华力,蛋白质的侧链必须被紧密地包装且不溶于任何能量不利地重叠。在...
网络蛋白质全新设计;从头蛋白设计 网络释义
Hallucination中看似简单的改动,就完成了自洽地生成蛋白结构和对应的序列,达到无中生有的境界,最后作者也提出了鲜明的观点,Hallucination+trDesign的设计方式完全可以来解决功能片段的融合设计问题,潜在的应用场景是酶设计、金属结合蛋白,以及蛋白binder设计,也是下一章节的主要内容。 3 trDesign-Motif 文献参考:Tischer D,...

Protein design aims to identify new protein sequences of desirable structure and biological function. Most current de novo protein design methods rely on physics-based force fields to search for low free-energy states following Anfinsen's thermodynamic hypothesis. A major obstacle of such approaches ...
De Novo Protein Design 在设计链A之前,首先让链条成为多丙氨酸,以便我们可以将侧链重新设计到主链上: # 在对pose进行操作之前,首先移除所有的限制 remove_constraints = pyrosetta.rosetta.protocols.constraint_generator.RemoveConstraints() remove_constraints.add_generator(coord_constraint_gen) ...
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 ...
Computational protein design is a reverse procedure of protein folding and structure prediction, where constructing structures from evolutionarily related proteins has been demonstrated to be the most reliable method for protein 3-dimensional structure prediction. Following this spirit, we developed a novel...
protein. This represents a stringent test of our understanding of the physicochemical determinants that drive biomolecular interactions11. Robust computational methods to design de novo PPIs could be used to rapidly engineer protein-based therapeutics such as antibodies and protein inhibitors or vaccines ...
