Abstract
Cytochrome P450 BM3 monooxygenase is the topic of extensive research as many researchers have evolved this enzyme to generate a variety of products. However, the abundance of information on increasingly diversified variants of P450 BM3 that catalyze a broad array of chemistry is not in a format that enables easy extraction and interpretation. We present a database that categorizes variants by their catalyzed reactions and includes details about substrates to provide reaction context. This database of >1500 P450 BM3 variants is downloadable and machine-readable and includes instructions to maximize ease of gathering information. The database allows rapid identification of commonly reported substitutions, aiding researchers who are unfamiliar with the enzyme in identifying starting points for enzyme engineering. For those actively engaged in engineering P450 BM3, the database, along with this review, provides a powerful and user-friendly platform to understand, predict, and identify the attributes of P450 BM3 variants, encouraging the further engineering of this enzyme.

Abstract
Peroxygenases are promising catalysts for use in the oxidation of chemicals as they catalyze the direct oxidation of a variety of compounds under ambient conditions using hydrogen peroxide (H2O2) as an oxidant. Although the use of peroxygenases provides a simple method for oxidation of chemicals, the anthraquinone process currently used to produce H2O2 requires significant energy input and generates considerable waste, which negatively affects process sustainability and production costs. Thus, generating H2O2 for peroxygenases on site using an environmentally benign method would be advantageous. Here, we utilized spent coffee grounds (SCGs) and tea leaf residues (TLRs) for the production of H2O2. These waste biomass products reacted with molecular oxygen and effectively generated H2O2 in sodium phosphate buffer. The resulting H2O2 was utilized by the bacterial P450 peroxygenase, CYP152A1. Both SCG-derived and TLR-derived H2O2 promoted the CYP152A1-catalyzed oxidation of 4-methoxy-1-naphthol to Russig's blue as a model reaction. In addition, when CYP152A1 was incubated with styrene, the SCG and TLR solutions enabled the synthesis of styrene oxide and phenylacetaldehyde. This new approach using waste biomass provides a simple, cost-effective, and sustainable oxidation method that should be readily applicable to other peroxygenases for the synthesis of a variety of valuable chemicals.

Abstract
Cytochrome P450 enzymes (CYPs) catalyze a series of C–H and C=C oxygenation reactions, including hydroxylation, epoxidation, and ketonization. They are attractive biocatalysts because of their ability to selectively introduce oxygen into inert molecules under mild conditions. This review provides a comprehensive overview of the C–H and C=C oxygenation reactions catalyzed by CYPs and the various strategies for achieving higher selectivity and enzymatic activity. Furthermore, we discuss the application of C–H and C=C oxygenation catalyzed by CYPs to obtain the desired chemicals or pharmaceutical intermediates in practical production. The rapid development of protein engineering for CYPs provides excellent biocatalysts for selective C–H and C=C oxygenation reactions, thereby promoting the development of environmentally friendly and sustainable production processes.

Abstract
Cytochrome P450 monooxygenases (P450s) are promising versatile oxidative biocatalysts. However, the practical use of P450s in vitro is limited by their dependence on the co-enzyme NAD(P)H and the complex electron transport system. Using H2O2 simplifies the catalytic cycle of P450s; however, most P450s are inactive in the presence of H2O2. By mimicking the molecular structure and catalytic mechanism of natural peroxygenases and peroxidases, an artificial P450 peroxygenase system has been designed with the assistance of a dual-functional small molecule (DFSM). DFSMs, such as N-(ω-imidazolyl fatty acyl)-l-amino acids, use an acyl amino acid as an anchoring group to bind the enzyme, and the imidazolyl group at the other end functions as a general acid-base catalyst in the activation of H2O2. In combination with protein engineering, the DFSM-facilitated P450 peroxygenase system has been used in various oxidation reactions of non-native substrates, such as alkene epoxidation, thioanisole sulfoxidation, and alkanes and aromatic hydroxylation, which showed unique activities and selectivity. Moreover, the DFSM-facilitated P450 peroxygenase system can switch to the peroxidase mode by mechanism-guided protein engineering. In this short review, the design, mechanism, evolution, application, and perspective of these novel non-natural P450 peroxygenases for the oxidation of non-native substrates are discussed.

Abstract
CYP102A1 (BM3) is a catalytically self-sufficient flavocytochrome fusion protein isolated from Bacillus megaterium, which displays similar metabolic capabilities to many drug-metabolizing human P450 isoforms. BM3's high catalytic efficiency, ease of production and malleable active site makes the enzyme a desirable tool in the production of small molecule metabolites, especially for compounds that exhibit drug-like chemical properties. The engineering of select key residues within the BM3 active site vastly expands the catalytic repertoire, generating variants which can perform a range of modifications. This provides an attractive alternative route to the production of valuable compounds that are often laborious to synthesize via traditional organic means. Extensive studies have been conducted with the aim of engineering BM3 to expand metabolite production towards a comprehensive range of drug-like compounds, with many key examples found both in the literature and in the wider industrial bioproduction setting of desirable oxy-metabolite production by both wild-type BM3 and related variants. This review covers the past and current research on the engineering of BM3 to produce drug metabolites and highlights its crucial role in the future of biosynthetic pharmaceutical production.

Abstract
Cytochrome P450 enzymes (P450s) are broadly distributed among living organisms and play crucial roles in natural product biosynthesis, degradation of xenobiotics, steroid biosynthesis, and drug metabolism. P450s are considered as the most versatile biocatalysts in nature because of the vast variety of substrate structures and the types of reactions they catalyze. In particular, P450s can catalyze regio- and stereoselective oxidations of nonactivated C-H bonds in complex organic molecules under mild conditions, making P450s useful biocatalysts in the production of commodity pharmaceuticals, fine or bulk chemicals, bioremediation agents, flavors, and fragrances. Major efforts have been made in engineering improved P450 systems that overcome the inherent limitations of the native enzymes. In this review, we focus on recent progress of different strategies, including protein engineering, redox-partner engineering, substrate engineering, electron source engineering, and P450-mediated metabolic engineering, in efforts to more efficiently produce pharmaceuticals and other chemicals. We also discuss future opportunities for engineering and applications of the P450 systems.

Abstract
Cytochrome P450 enzymes (P450s) catalyze the monooxygenation of various organic substrates. These enzymes are fascinating and promising biocatalysts for synthetic applications. Despite the impressive abilities of P450s in the oxidation of C-H bonds, their practical applications are restricted by intrinsic drawbacks, such as poor stability, low turnover rates, the need for expensive cofactors (e.g., NAD(P)H), and the narrow scope of useful non-native substrates. These issues may be overcome through the general strategy of protein engineering, which focuses on the improvement of the catalysts themselves. Alternatively, several emerging strategies have been developed that regulate the P450 catalytic process from the viewpoint of the substrate. These strategies include substrate engineering, decoy molecule, and dual-functional small-molecule co-catalysis. Substrate engineering focuses on improving the substrate acceptance and reaction selectivity by means of an anchoring group. The latter two strategies utilize co-substrate-like small molecules that either are proposed to reform the active site, thereby switching the substrate specificity, or directly participate in the catalytic process, thereby creating new catalytic peroxygenation capabilities towards non-native substrates. For at least 10 years, these approaches have played unique roles in solving the problems highlighted above, either alone or in conjunction with protein engineering. Herein, we review three strategies for substrate regulation in the P450-catalyzed oxidation of non-native substrates. Furthermore, we address remaining challenges and potential solutions associated with these approaches.

Abstract
Cytochromes P450 (P450 or CYP) are heme-containing enzymes that catalyze the introduction of one atom of molecular oxygen into nonactivated C-H bonds, often in a regio- and stereoselective manner. This ability, combined with a tremendous number of accepted substrates, makes P450s powerful biocatalysts. Sixty years after their discovery, P450 systems are recognized as essential bio-bricks in synthetic biology approaches to enable production of high-value complex molecules in recombinant hosts. Recent impressive results in protein engineering led to P450s with tailored properties that are even able to catalyze abiotic reactions. The introduction of P450s in artificial multi-enzymatic cascades reactions and chemo-enzymatic processes offers exciting future perspectives to access novel compounds that cannot be synthesized by nature or by chemical routes.

Abstract
The biological production of ethanol from ethane for the utilization of ethane in natural gas was investigated under ambient conditions using whole-cell methanotrophs possessing methane monooxygenase. Several independent variables including ethane concentration and biocatalyst amounts, among other factors, were optimized for the enhancement of ethane-to-ethanol bioconversion. We obtained 0.4 g/L/h of volumetric productivity and 0.52 g/L of maximum titer in optimum batch reaction conditions. In this study, we demonstrate that the biological gas-to-liquid conversion of ethane to ethanol has potent technical feasibility as a new application of ethane gas.

Abstract
Bacterial cytochrome P450 monooxygenases (P450s) are promising biocatalysts for chemical syntheses because they catalyze a variety of oxidations on non-activated hydrocarbons using O2 . However, the requirement of two auxiliary proteins, an electron transfer protein and a reductase, for the catalysis is a major bottleneck for in vitro applications of these monooxygenases. The authors previous study showed that artificial assembly of a bacterial P450 with its auxiliary proteins using a heterotrimeric proliferating cell nuclear antigen (PCNA) from Sulfolobus solfataricus yields a self-sufficient P450, but partial dissociation of P450 from the complex at catalytic concentrations reduces the apparent specific activity of this self-sufficient P450. In this study, a Metallosphaera sedula PCNA is used, which is currently the most stable heterotrimeric PCNA, to assemble a bacterial P450 with its auxiliary proteins at submicromolar protein concentrations. The apparent specific monooxygenase activity of the M. sedula PCNA-assembled P450 with auxiliary proteins is saturated at protein concentrations of 40 nM, and is 2.1-fold higher than that of the S. solfataricus PCNA-assembled P450. Therefore, M. sedula PCNA represents a versatile tool to facilitate multiple enzymatic reactions, including the P450 monooxygenase system.
