Here, we report on the genome-guided discovery and functional characterization of bacterial UbiA diterpene synthases (diTSs). Using a geranylgeranyl diphosphate (GGPP)-overproducing <i>Escherichia coli</i> system, we screened 32 candidate enzymes and identified five that generate structurally diverse diterpenes, two of which represent bacterial examples of cyathane synthases. Site-directed mutagenesis uncovered active-site residues that influence product formation, directing cyclization toward mono- or tricyclic products. This study expands the known catalytic repertoire of UbiA enzymes and highlights their untapped potential in bacterial terpenoid biosynthesis.

However, modern methodology is limited by reliance on expensive transition metal catalysts or slow reactivity. While selenium-catalyzed methods avoid some of these issues, in their current state, they require high catalyst loadings (15 mol %), superstoichiometric quantities of the amine and oxidant source, and long reaction times. Furthermore, our understanding of the mechanism remains incomplete: e.g., what is the catalytically active species, how is the precatalyst converted to it, and what is the role of the ligand? In this paper, we report an <i>N</i>-heterocyclic carbene selenide (NHC-Se) that allows for substantially reduced loadings of selenium without sacrificing reaction time, improves conversions and yields for challenging substrates, and even exhibits the capacity to catalyze 1,4-allylic diamination of alkenes. To understand the origin of the enhanced activity compared to the state-of-the-art NHC-Se precatalyst, we conducted a mechanistic study that supports ligand-free selenium diimide as the active enophile in these systems, while the NHC-derived byproducts, like the corresponding urea, facilitate turnover. We also isolate and structurally characterize NHC-Se mono- and diimido species and explore their mechanistic role.

To address this gap, we reanalyzed all available structural information and, integrating experimental data with multiscale molecular simulations, successfully modeled the full-length structure of hCHIT1 for the first time, including the previously unresolved proline-rich linker essential for domain communication. This comprehensive model enabled us to propose a general mechanism of hCHIT1 catalysis and to elucidate the distinct functional roles of all four highly conserved structural motifs of the glycoside hydrolase 18 (GH18) family, a group comprising over 65,000 known members across all domains of life. We further investigated the influence of monovalent metal ions in achieving optimal catalytic conditions and determined the activation energies for both substrate-assisted hydrolysis and transglycosylation processes. Our simulations revealed coordinated Brownian conformational fluctuations within hCHIT1 subdomains, which collectively harness thermal energy to drive catalysis. Notably, we discovered a previously unreported piston-like mechanism in which a conserved tyrosine residue transduces mechanical energy to the substrate, significantly lowering the activation barrier for catalysis. Additionally, by constructing a complete substrate model, we resolved the long-standing mechanistic enigma of the highly conserved tryptophan ‘lid’ at the active site entrance, demonstrating its multifaceted role in substrate gating, transition state stabilization, and product release. Finally, we demonstrated that binding of the first-in-class inhibitor OATD-01 induces subtle yet far-reaching dynamical changes within the active site, leading to dissociation of the immunoglobulin-like heterodimer and disruption of interactions with biological partners implicated in disease pathogenesis.
