We show that the top performing graph neural network potential trained on the OC20 data set, a related but different task, is able to find transition states energetically similar (within 0.1 eV) to density functional theory (DFT) 91% of the time with a 28× speedup. This speaks to the generalizability of the models, having never been explicitly trained on reactions, the machine learned potential approximates the potential energy surface well enough to be performant for this auxiliary task. We introduce the Open Catalyst 2020 Nudged Elastic Band (OC20NEB) data set, which is made of 932 DFT nudged elastic band calculations, to benchmark machine learned model performance on transition state energies. To demonstrate the efficacy of this approach, we for the first time explicitly treated a large reaction network with 61 intermediates and 174 dissociation reactions at DFT resolution (40 meV). To find low energy transition states we densely enumerate many possible NEBs. Using DFT this would have taken 52 GPU years. With ML we realized a 1500× speedup for dense enumerations, using just 12 GPU days of compute. Similar searches for complete reaction networks could become routine using the approach presented here. Finally, we constructed an ammonia synthesis activity volcano and systematically found lower energy configurations of the transition states and intermediates on six stepped unary surfaces than had previously been reported. This scalable approach offers a more complete treatment of configurational space to improve and accelerate catalyst discovery.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"18 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They feature two characteristic sequence motifs that distinguish them from homologous short-chain dehydrogenases and reductases. Sequence motif 1, carrying a conserved threonine, glycine, and a central aromatic residue, lines the nucleophile binding pocket of HHDHs. It could therefore impact nucleophile binding and presumably also the activity of the enzymes. However, experimental evidence supporting this theory is largely missing. Herein, we systematically studied the mutability of the three conserved motif 1 residues as well as their resulting impact on enzyme activity, stability, and selectivity in two model HHDHs: HheC from <i>Agrobacterium radiobacter</i> AD1 and HheG from <i>Ilumatobacter coccineus</i>. In both HheC and HheG, the conserved threonine and glycine tolerated mutations to only structurally similar amino acids. In contrast, the central aromatic (i.e., phenylalanine or tyrosine) residue of motif 1 demonstrated much higher variability in HheC. Remarkably, some of these variants featured drastically altered activity, stability, and selectivity characteristics. For instance, variant HheC F12Y displayed up to 5-fold increased specific activity in various epoxide ring opening and dehalogenation reactions as well as enhanced enantioselectivity (e.g., an <i>E</i>-value of 74 in the azidolysis of epichlorohydrin compared to <i>E</i> = 22 for HheC wild type) while also exhibiting a 10 K higher apparent melting temperature. QM and MD simulations support the experimentally observed activity increase of HheC F12Y and reveal alterations in the hydrogen bonding network within the active site. As such, our results demonstrate that multiple enzyme properties of HHDHs can be altered through the targeted mutagenesis of conserved motif 1 residues. In addition, this work illustrates that motif 1 plays vital roles beyond nucleophile binding by impacting the solubility and stability properties. These insights advance our understanding of HHDH active sites and will facilitate their future engineering.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"32 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbene insertion products can be obtained with high chemical selectivity, regioselectivity, <i>Z/E</i> selectivity, and enantioselectivity using α-diazo esters and enone-hydrazones under the conditions of a chiral dirhodium catalyst. The mechanism verification experiments demonstrate that the benzene ring, originating from the enone-hydrazones, can shield the O and NH coordination atoms of the enone-hydrazones. This shielding effect is crucial for the asymmetric C–C bond insertion reaction catalyzed by a chiral metal carbene complex derived from a chiral dirhodium. Additionally, the results of the controlled experiments indicate that achieving the asymmetric version of the traditional C–C insertion substrate is challenging. This challenge arises from the coordination of the substrate with the Rh1 site of the chiral dirhodium catalyst, which subsequently leads to carbene precursor activation occurring at the Rh2 site, resulting in poor stereoselectivity.","PeriodicalId":9,"journal":{"name":"ACS Catalysis ","volume":"69 1","pages":""},"PeriodicalIF":12.9,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is often not feasible to use CYPs in larger-scale synthesis as they require additional cofactors (NAD(P)H) and electron transfer proteins. This could be overcome by transforming CYPs into peroxygenases that use H₂O₂. Recently, multiple strategies have been reported for converting CYPs into peroxygenases. Mutating the residues of the acid–alcohol pair in the oxygen-binding groove to those found in natural peroxygenases can promote the desired H₂O₂-driven activity. Another strategy is to enlarge the enzyme’s solvent channels to allow H₂O₂ easier access into the active site, to enhance peroxygenase activity. Here, we evaluate these different strategies by comparing the peroxygenase activities of the double I-helix mutant D251Q/T252E (the QE mutant) and the F182A mutant of the bacterial enzyme CYP199A4. We also assess whether the peroxygenase activity can be further improved by combining these mutations (to give the F182AQE mutant). The F182A mutant exhibited the highest activity toward a selection of smaller substrates that undergo <i>O</i>-demethylation, <i>S</i>-oxidation, and epoxidation reactions. All the mutants converted 4-vinylbenzoic acid into the (<i>S</i>)-epoxide, with the F182A mutant having the highest stereoselectivity (&gt;99% ee).

The F182A mutant catalyzed significant further oxidation reactions of the primary metabolites before all the substrate had been consumed, demonstrating a relaxed substrate specificity.
