Our latest paper "Enzyme Enhancement Through Computational Stability Design Targeting NMR-Determined Catalytic Hotspots" now out in JACS @jacs.acspublications.org. Collaboration with Jose M. Sanchez-Ruiz in Granada, among others. pubs.acs.org/doi/full/10....

pubs.acs.orgEnzyme Enhancement Through Computational Stability Design Targeting NMR-Determined Catalytic HotspotsEnzymes are the quintessential green catalysts, but realizing their full potential for biotechnology typically requires improvement of their biomolecular properties. Catalysis enhancement, however, is often accompanied by impaired stability. Here, we show how the interplay between activity and stability in enzyme optimization can be efficiently addressed by coupling two recently proposed methodologies for guiding directed evolution. We first identify catalytic hotspots from chemical shift perturbations induced by transition-state-analogue binding and then use computational/phylogenetic design (FuncLib) to predict stabilizing combinations of mutations at sets of such hotspots. We test this approach on a previously designed de novo Kemp eliminase, which is already highly optimized in terms of both activity and stability. Most tested variants displayed substantially increased denaturation temperatures and purification yields. Notably, our most efficient engineered variant shows a ∼3-fold enhancement in activity (kcat ∼ 1700 s–1, kcat/KM ∼ 4.3 × 105 M–1 s–1) from an already heavily optimized starting variant, resulting in the most proficient proton-abstraction Kemp eliminase designed to date, with a catalytic efficiency on a par with naturally occurring enzymes. Molecular simulations pinpoint the origin of this catalytic enhancement as being due to the progressive elimination of a catalytically inefficient substrate conformation that is present in the original design. Remarkably, interaction network analysis identifies a significant fraction of catalytic hotspots, thus providing a computational tool which we show to be useful even for natural-enzyme engineering. Overall, our work showcases the power of dynamically guided enzyme engineering as a design principle for obtaining novel biocatalysts with tailored physicochemical properties, toward even anthropogenic reactions.

Big news: we are setting up a new non-profit organization to run bioRxiv and medRxiv. It's called openRxiv [no it's not a new preprint server; it's dedicated organization to oversee the servers] openrxiv.org 1/n

openrxiv.orgHomepage - openRxivopenRxiv is an independent non-profit, the new organizational home for bioRxiv and medRxiv, enabling researchers to instantly share groundbreaking findings with the global scientific community.

This work is now published in J Phys Chem B! Check out our work showing that simulations predict the impact of distal mutations on kinase-inhibitor binding, and our experimental NanoBRET dataset of 94 kinase mutations that provide a benchmark for future methods. Link: pubs.acs.org/doi/full/10....

Sukrit Singh@sukritsingh92.bsky.social

New preprint! We prospectively evaluate structure-based methods and measure how well they classify clinical kinase mutations as inhibitor–resistant or –sensitizing when compared against our NanoBRET assay. Alchemical methods are well-suited to modeling distal mutants! Link: doi.org/10.1101/2024...

Breaking news: A judge has issued a national preliminary injunction blocking Trump cuts to NIH research overhead payments, a decision that suggests plaintiffs seeking to overturn the policy change are likely to eventually succeed. My latest for @statnews.com www.statnews.com/2025/03/05/n...
