Reprogramming the Rossmann fold signature motif creates orthogonal redox biocatalysts

Biological reducing power is carried by nicotinamide adenine dinucleotide (phosphate) (NAD(P)/H), which supports cellular functions and cannot be specifically directed to engineered metabolic pathways. Nicotinamide mononucleotide (NMN(H)) has emerged as an orthogonal redox cofactor to address this. Herein, to create...

A sequence motif enables widespread use of noncanonical redox cofactors in natural enzymes.

Noncanonical redox cofactors (NRCs) are low-cost alternatives to the natural redox cofactors nicotinamide adenine dinucleotide (NAD+) and nicotinamide adenine dinucleotide phosphate (NADP+) for biomanufacturing, offering exquisite electron-delivery control, yet their adoption is limited by the scarcity of compatible en...

Flux Rewiring Enables Native D-Glucosamine Production in Escherichia coli.

Native amino sugar biosynthesis in E. coli provides a controllable framework for producing chemically distinct sugars through endogenous metabolism and establishes a generalizable strategy for engineering amino sugar and other nitrogen-containing metabolite biosynthesis.

De novo Rubisco design with protein language models

Together, these results establish a scalable strategy for accessing previously unexplored Rubisco sequence space, providing a broadly accessible path toward generating de novo Rubiscos that have activity and specificity parameters needed to address longstanding limitations in biological carbon fixation.
