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
Covalent linkage between the single-walled carbon nanotube (SWCNT) and CYP101 through a specific site of the enzyme can provide a novel method of designing efficient enzyme electrodes using this prototype cytochrome P450 enzyme. We have chemically modified the SWCNT with linker 4-carboxy phenyl maleimide (CPMI) containing maleimide functional groups. The enzyme was covalently attached on to the SWCNT through the maleimide group of the linker (CPMI) to the thiolate group of the surface exposed Cys 58 or Cys 136 of the CYP101 forming a covalently immobilized protein on the nanotube. Thin film of the modified SWCNT-CPMI-CYP101conjugate was made on a glassy carbon (GC) electrode. Direct electrochemistry of the substrate (camphor)-bound enzyme was studied using this immobilized enzyme electrode system and the redox potential was found to be -320mV vs Ag/AgCl (3 M KCl), which agrees with the redox potential of the substrate bound enzyme reported earlier. The electrochemically driven enzymatic mono-oxygenation of camphor by this immobilized enzyme electrode system was studied by measurement of the catalytic current at different concentrations of camphor. The catalytic current was found to increase with increasing concentration of camphor in presence of oxygen. The product formed during the catalysis was identified by mass-spectrometry as hydroxy-camphor.

Precise and rapid solvent-assisted geometric protein self-patterning with submicron spatial resolution for scalable fabrication of microelectronic biosensors. Biosens Bioelectron 2021; 177:112968. [PMID: 33450615 DOI: 10.1016/j.bios.2021.112968] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 12/08/2020] [Accepted: 01/01/2021] [Indexed: 11/22/2022]
Abstract
Precise and high-resolution coupling of functional proteins with micro-transducers is critical for the manufacture of miniaturized bioelectronic devices. Moreover, electrochemistry on microelectrodes has had a major impact on electrochemical analysis and sensor technologies, since the small size of microelectrode affects the radial diffusion flux of the analyte to deliver enhanced mass transport and electrode kinetics. However, a large technology gap has existed between the process technology associated with such microelectronics and the conventional bio-conjugation techniques that are generally used. Here, we report on a high-resolution and rapid geometric protein self-patterning (GPS) method using solvent-assisted protein-micelle adsorption printing to couple biomolecules onto microelectrodes with a minimum feature size of 5 μm and a printing time of about a minute. The GPS method is versatile for micropatterning various biomolecules including enzymes, antibodies and avidin-biotinylated proteins, delivering good geometric alignment and preserving biological functionality. We further demonstrated that enzyme-coupled microelectrodes for glucose detection exhibited good electrochemical performance which benefited from the GPS method to maximize effective signal transduction at the bio-interface. These microelectrode arrays maintained fast convergent analyte diffusion displaying typical steady-state I-V characteristics, fast response times, good linear sensitivity (0.103 nA mm-2 mM-1, R2 = 0.995) and an ultra-wide linear dynamic range (2-100 mM). Our findings provide a new technical solution for the precise and accurate coupling of biomolecules to a microelectronic array with important implications for the scaleup and manufacture of diagnostics, biofuel cells and bioelectronic devices that could not be realized economically by other existing techniques.

Surface charge-controlled electron transfer and catalytic behavior of immobilized cytochrome P450 BM3 inside dendritic mesoporous silica nanoparticles. Anal Bioanal Chem 2020; 412:4703-4712. [PMID: 32483647 DOI: 10.1007/s00216-020-02727-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 05/14/2020] [Accepted: 05/19/2020] [Indexed: 10/24/2022]
Abstract
Understanding the influencing factors on the reaction kinetics of P450 BM3 within confined spaces is essential for developing efficient P450 BM3 bioreactors. Herein, two dendritic mesoporous silica nanoparticles (OH-DMSNs and NH2-DMSNs) with similar pore size but opposite surface charge have been prepared and served as the vehicle to immobilize P450 BM3. With the help of the film-forming material of chitosan, P450 BM3/OH-DMSN and P450 BM3/NH2-DMSN composites were immobilized on GC electrode and characterized with electrochemical measurements. Compared with P450 BM3/OH-DMSNs/GCE, P450 BM3/NH2-DMSNs/GCE showed higher electron transfer efficiency with higher current charge and lower ks value. Besides, the generated catalytic current towards testosterone on P450 BM3/NH2-DMSNs/GCE was 1.81 times larger than P450 BM3/OH-DMSNs/GCE. Furthermore, P450 BM3 inside NH2-DMSNs displayed higher affinity towards testosterone with the lower Kmapp value of 244.82 μM. These results are attributed to the positively charged internal walls of NH2-DMSNs so that P450 BM3 adapts to an orientation favorable for electron exchange with electrodes and substrate binding with the active sites. The present study provides fundamentals for regulating the surface charge to optimize redox process and catalytic behavior in CYP bioreactors through electrostatic interactions.

Abstract
Electrochemical in vitro reduction of P450 enzymes is a promising alternative to in vivo applications. Previously we presented three engineered P450BM3 variants for aniline hydroxylation, equipped with a carbon nanotube binding-peptide (CNT-tag) for self-assembly on CNT electrodes. Compared to wildtype P450BM3 the NADPH-dependent activity was enhanced, but the coupling efficiency remained low. For P450BM3 Verma, Schwaneberg and Roccatano (2014, Biopolymers 101, 197-209) calculated putative electron transfer pathways (eTPs) by MD simulations. We hypothesised that knockouts of these transfer pathways would alter the coupling efficiency of the system. The results revealed no improved system for the electrically-driven P450s. For the NADPH-driven P450s, however, the most active eTP-mutant showed a 13-fold increased activity and a 32-fold elevated coupling efficiency using NADPH as reducing equivalent. This suggests an alternative principle of electron transport for the reduction by NADPH and an electrode, respectively. The work presents moreover a tool to improve the coupling and activity of P450s with non-natural substrates.
