Enzyme self-assembly is a technology in which enzyme units can aggregate into ordered macromolecules, assisted by scaffolds. In metabolic engineering, self-assembly strategies have been explored for aggregating multiple enzymes in the same pathway to improve sequential catalytic efficiency, which in turn enables high-level production. The performance of the scaffolds is critical to the formation of an efficient and stable assembly system. This review comprehensively analyzes these scaffolds by exploring how they assemble, and it illustrates how to apply self-assembly strategies for different modules in metabolic engineering. Functional modifications to scaffolds will further promote efficient strategies for production.

Riboflavin, an important vitamin utilized in pharmaceutical products and as a feed additive, is mainly produced by metabolically engineered bacterial fermentation. However, the reliance on antibiotics in the production process leads to increased costs and safety risks. To address these challenges, an antibiotic-free riboflavin producer was constructed using metabolic engineering approaches coupled with a novel plasmid stabilization system.

The regulation of cellular metabolism is crucial for cell survival, with Sch9 in serving a key role as a substrate of TORC1. Sch9 localizes to the vacuolar membrane through binding to PI(3,5)P, which is necessary for TORC1-dependent phosphorylation. This study demonstrates that cytosolic pH regulates Sch9 localization.

Lignin valorization is crucial for achieving economic and sustainable biorefinery processes. However, the enzyme substrate preferences involved in lignin degradation remain poorly understood, and low activity toward specific substrates presents a significant challenge to the efficient utilization of lignin. In this study, we investigated the substrate promiscuity of Ado, a key enzyme involved in lignin valorization.

Background: Pulmonary arterial hypertension (PAH) is a deadly disease without effective non-invasive diagnostic and prognostic testing. It remains unclear whether vasodilators reverse inflammatory activation, a part of PAH pathogenesis. Single-cell profiling of inflammatory cells in blood could clarify these PAH mechanisms.

Neuromuscular controllers (NMCs) offer a promising approach to adaptive and task-invariant control of exoskeletons for walking assistance, leveraging the bioinspired models based on the peripheral nervous system. This article expands on our previous development of a novel structure for NMCs with modifications to the virtual muscle model and reflex modulation strategy. The modifications consist firstly of simplifications to the Hill-type virtual muscle model, resulting in a more straightforward formulation and reduced number of parameters; and second, using a finer division of gait subphases in the reflex modulation state machine, allowing for a higher degree of control over the shape of the assistive profile.
