Amino acid residues distant from an enzyme's active site are known to influence catalysis, but their mechanistic contributions to the catalytic cycle remain poorly understood. Here, we investigate the structural, functional, and mechanistic impacts of distal and active-site mutations discovered through directed evolution of the computationally designed retro-aldolase RA95. Active-site mutations improve catalytic efficiency by 3,600-fold, while distal mutations alone offer no improvement.

Chronic respiratory diseases such as asthma and COPD involve interactions between multiple resident and immune cell types within bronchial airways, resulting in structural and functional changes. Thus cellular heterogeneity, arrangements and associated neighborhoods as well as interactions between cells and matrices represent intriguing yet challenging areas of study. Spatial phenotypic profiling facilitates exploration of these issues of the cellular microenvironment and identification of context-dependent cell-cell interactions.

This study aims to develop a robust and reproducible method for fabricating efficient ultrathin antifouling coatings on gold surfaces by leveraging hydroxylation-based surface modifications. An ultrathin antifouling coating of a monoethylene glycol silane derivative, known to reduce fouling by at least 90% on flat hydroxylated surfaces, was successfully replicated on flat gold (reducing fouling by ~75%) by hydroxylating its surface with β-mercaptoethanol. This tandem coating contains the monoethylene glycol silane layer on top of the β-mercaptoethanol on the gold.

Preserving a contamination-free metal-semiconductor interface in -GaO is critical to achieve consistently low resistance ( 1 Ω-mm) ohmic contacts. Here, we report a scanning transmission electron microscopy study on the variation in Ti/Au ohmic contact quality to (010) -GaO in a conventional lift-off vs a metal-first process. We observe a thin ∼1 nm carbon barrier between the Ti and GaO in a non-conductive contact fabricated by a conventional lift-off process, which we attribute to photoresist residue, not previously detected by x-ray photoelectron spectroscopy due to the thinness and patchy coverage of the carbon layer, as well as roughness of the GaO surface.

Endothelial-to-mesenchymal transition (EndMT) is a biological process that converts endothelial cells to mesenchymal cells with increased proliferative and migrative abilities. EndMT has been implicated in the development of pulmonary vascular remodeling in pulmonary arterial hypertension (PAH), a fatal and progressive lung vascular disease. Transforming growth factor β (TGF-β), an inflammatory cytokine, is known to induce EndMT in many types of endothelial cells including lung vascular endothelial cells (LVECs).
