We set out to de novo design Ig fold structures, and began by considering the key aspects of the fold. The basic Ig domain10,11 is a β-sandwich formed by 7-to-9 β-strands arranged in two antiparallel β-sheets facing each other, and connected through β-hairpins (within the same ...
We describe a de novo computational approach for designing proteins that recapitulate the binding sites of natural cytokines, but are otherwise unrelated in topology or amino acid sequence. We use this strategy to design mimics of the central immune cytokine interleukin-2 (IL-2) that bind to the...
Here we show that a general class of protein-based biosensors can be created by inverting the flow of information through de novo designed protein switches in which the binding of a peptide key triggers biological outputs of interest. The designed sensors are modular molecular devices with a ...
It is accomplished either from scratch or by the modular approach. The full de novo peptide design framework consists of three stages: an optimization-based sequence selection, fold specificity calculation, and approximate binding affinity calculation. The full framework of the method is shown in Fig...

The de novo design of miniature protein scaffolds, can be a powerful tool with which to answer important questions about protein structure and function. Similarly the design of metallopeptides de novo provides an opportunity to interrogate the role of the protein matrix in tuning the chemistries of...

de novo peptide sequencing algorithms的原理De novo peptide sequencing 指的是从原始蛋白质混合物中从头测序肽段的过程。这个过程主要包括以下几个步骤: 1. 蛋白质消化:首先,将蛋白质样品酶解成小肽段。这一步通常使用蛋白酶(如胰蛋白酶、胃蛋白酶等)来将蛋白质分解成肽段。 2. 肽段分离:消化后的混合物中...
