Alliin (S-allyl-l-cysteine sulfoxide) is a valuable bioactive sulfur compound and an allicin precursor. However, its biocatalytic synthesis is limited by poor stereocontrol of an Fe2+/α-ketoglutarate-dependent dioxygenase (l-isoleucine dioxygenase, IDO) that converts S-allyl-l-cysteine (SAC) into alliin. Herein, we a...

S-Allyl-l-cysteine (SAC) is a bioactive organosulfur compound from aged garlic that has attracted considerable interest for its health-promoting properties. Here, we developed a channel-guided engineering strategy to enhance SAC biosynthesis using the β-subunit of tryptophan synthase (TrpB). Genome mining guided by c...

ABSTRACT Enzyme turnover number (kcat) is a central kinetic parameter for biocatalysis, but experimental determination is low‐throughput and existing computational methods inadequately model enzyme–reaction interplay. Here, we introduced MCKcat, a deep learning framework that integrates multi‐scale convolutional featur...

Lignocellulose is an abundant renewable feedstock for biofuels and value-added bioproducts, yet its efficient bioconversion is hindered by the recalcitrant lignin barrier. While laccases show great potential for lignin modification and delignification, their limited thermostability restricts their application in high-t...
