We explored this approach by merging a tripeptide catalyst with an alcohol dehydrogenase as a case study to bring together the strengths of enzymatic redox chemistry and peptide-catalyzed carbon–carbon bond formation. A proline-based peptide catalyst for C─C bond formation relying on an enamine intermediate was successfully merged to the N-terminus of an alcohol dehydrogenase to catalyze a cascade involving alcohol oxidation followed by C─C bond formation. It turned out that the reaction speed of the two catalytic sites diverged, and the ε-amino group of lysine residues present in the enzyme interfered with the organocatalytic proline activity. Removing/exchanging lysine residues within the enzyme reduced the background reaction but also the native redox activity. Interestingly, exchanging the N-terminal proline with a histidine switched the stereopreference. The simultaneous cascade reaction of alcohol oxidation to the aldehyde and C─C bond formation with nitrostyrene presents a first proof-of-concept for bringing peptide catalysis together with enzyme catalysis and creating a bi-active site catalyst within a single domain.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 14","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202500539","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144663744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While it is known that they are concurrently generated from NO and thiols with the assistance of ferric heme complexes, the specific mechanisms of their formation in vivo remain a topic of debate. Here, we describe the formation mechanism of both RSNOs and NO-ferroheme, utilizing a thiolate-bound ferric TMPS porphyrin model system [Fe(TMPS)(SR)], where TMPS stands for meso-tetrakis(sulfonatomesityl)porphyrinato-iron(III), under aqueous, buffered conditions. Spectroscopic studies (Raman, EPR, UV–vis) using biologically relevant thiols (RS), including glutathione, cysteine, and N-acetylcysteine, revealed that heme-thiolate ([Fe3+(TMPS)(SR)]) exists in equilibrium with its valence tautomer, thiyl radical-bound ferrous ([Fe2+(TMPS)(SR•)]) species. However, the dominant reaction pathway is not the attack on the thiyl radical but rather the coordination of NO to the iron center, which results in the formation of a ferric nitrosyl species [Fe(TMPS)(SR)(NO)]. In a subsequent, slower step, the transient [Fe(TMPS)(SR)(NO)] converts to a NO-ferroheme through the direct attack of a second NO molecule on the coordinated thiolate, simultaneously releasing S-nitrosothiol. Experimental and theoretical studies showed that the generation of S-nitrosothiols follows a concerted reaction mechanism without the formation of iron coordinated S-nitrosothiol intermediate.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 17","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144997914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we proposed a novel process that integrated in situ substrate absorption using an organic solvent with enzymatic degradation, using haloalkane dehalogenase LinB as a model enzyme, 1-bromobutane as a volatile haloalkane, and n-dodecane as the absorbent. An amphiphilic polymer, Pluronic F127, was grafted onto LinB, resulting in the Pluronic-LinB conjugate being anchored at the n-dodecane/water interface, as evidenced by confocal laser scanning microscopy. The interfacial anchoring facilitated the uptake of 1-bromobutane by LinB, thereby enhancing catalytic hydrolysis. Pluronic-LinB exhibited a significantly enhanced flexibility at the n-dodecane/water interface, as shown by low-field nuclear magnetic resonance. All these increased enzymatic performances, as could be interpreted from the kinetic parameters. Moreover, molecular dynamic simulations revealed that the attached polymer enhanced the conformational dynamics of helix and loop motifs forming the substrate channels of the enzyme, increased the water flux, and reduced the residence time of water molecules in the active pocket.

The catalytic results reported that furan-2-acrolein is the main product with a maximum yield of 52% after 6 h of reaction at 130 °C for the catalyst with the highest Pd content.

Transition metal phosphides, particularly cobalt phosphide (CoP) have attracted significant interest due to their high theoretical capacity and excellent redox activity. However, their practical application is limited by poor cycling stability and lower electrical conductivity. To address these challenges, this study employs a metal-organic framework (ZIF-67) as a precursor to synthesize CoP, followed by the in- situ heterojunction formation (CoP/50-Ti3C2Tx, CoP/100-Ti3C2Tx, and CoP/150-Ti3C2Tx) with different mass loading (50, 100, and 150 mg) of MXene (Ti3C2Tx). The optimized electrode material CoP/100-Ti3C2Tx achieve the highest specific capacitance of 625.9 F/g at 0.25 A/g with a high rate performance of 260.2 F/g at 25 A/g. This performance significantly surpasses bare CoP (397.3 F/g at 0.25 A/g), Ti3C2Tx (106.3 F/g at 0.25 A/g), and other CoP/Ti3C2Tx composite. Additionally, it demonstrates a cycling stability of 78.13% for 10,000 cycles at 20 A/g. Furthermore, an asymmetric supercapacitor device was fabricated using CoP/100-Ti3C2Tx as positive electrode materials and activated carbon as the negative electrode. The as-fabricated device delivered an energy density of 22.59 Wh/kg at a power density of 399.99 W/kg with capacitance retention of 73.25% after 2000 cycles at 10 A/g and Coulombic efficiency close to 100%.

This study aims to present a structured, comprehensive method for the evaluation and comparison of immobilized enzyme processes. We identified 7 distinct process phases, each described by key performance indicators (KPIs), and showcase the evaluation in two case studies. In order to gain a complete insight, we then defined and calculated the meta KPIs “recovered activity efficiency”, “space time activity”, “total volumetric turnovers”, and “total process productivity” by assessing the formally calculated KPIs for an efficiency-based evaluation approach. We also utilized the E Factor analysis as a sustainability-based evaluation approach to estimate environmental impacts. We showed that only a holistic view of all phases, by comparison of meta KPIs, allows for accurate comparison of the processes. Additionally, the structured evaluation can be used as a tool for the identification of weak points in each process to elucidate paths for improvement.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 14","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202500699","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144663743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
