Article Abstract
Directed molecular evolution is the key technology for obtaining enzymes, proteins, metabolic pathways, and other components of living organisms that have specific functions or desirable properties, which are indispensable in a variety of industrial and medical applications. Despite the success of traditional methods, they are often limited by low efficiency and the high cost of obtaining desired mutants. The advent of CRISPR technology has significantly advanced the field by enabling precise and efficient gene targeting, offering new prospects for directed evolution. This review provides a comprehensive overview of CRISPR tools and their applications in directed evolution, highlighting the principles, technological advancements, and specific applications of CRISPR-based mutation and screening platforms. We discuss the key findings from the use of CRISPR in enzyme and genome evolution, showcasing its ability to generate genetic diversity and select for improved phenotypes. The study underscores the unique value of CRISPR in directed evolution, particularly in its flexibility to target and edit various species' genomes, and its potential to accelerate the discovery of novel biomolecules with enhanced properties.

ConspectusMolecular photochemistry, by harnessing the excited states of organic molecules, provides a platform fundamentally distinct from thermochemistry for generating reactive open-shell or spin-active species under mild conditions. Among its diverse applications, the resurgence of the Minisci-type reaction, a transformation historically reliant on thermally initiated radical conditions, has been fueled by modern photochemical strategies with improved efficiency and selectivity. Consequently, the photochemical Minisci-type reaction ranks among the most enabling methods for C()-H functionalizations of heteroarenes, which are of particular significance in medicinal chemistry for the rapid diversification of bioactive scaffolds.

Developing cost-effective spinel oxide catalysts with both high oxygen evolution reaction (OER) activity and stability is crucial for advancing sustainable clean energy conversion. However, practical applications are often hindered by the activity limitations inherent in the adsorbate evolution mechanism (AEM) and the stability limitations associated with the lattice oxygen mechanism (LOM). Herein, we demonstrate structural changes induced by phase transformation in CoMn spinel oxides, which yield more active octahedral sites with shortened intersite distance.

Synthetic biology often employs heterologous enzymatic reactions to reprogram cell metabolism or otherwise introduce novel functions. However, precise control of a particular metabolic pathway can be difficult to achieve because cofactors are shared with endogenous enzymes from a common pool. Recently, the use of noncanonical cofactors (NCCs) has emerged as a promising approach to bypass this problem by isolating desired reactions without the need for a physical barrier.
