Abstract
Hydrogenases are enzymes that catalyze the reversible conversion of protons to hydrogen gas, using earth-abundant metals such as nickel and/or iron. This characteristic makes them promising for sustainable energy applications, particularly in clean hydrogen production. However, their widespread use faces challenges, including a limited pH range and susceptibility to oxygen. In response to these issues, SacCoMyo is introduced as an artificial enzyme. SacCoMyo is designed by replacing the native metal in the myoglobin (Myo) scaffold with a hydroxocobalamin (Co) porphyrin core and complemented by a protective heteropolysaccharide-linked (Sac) shell. This engineered protein proves to be resilient, maintaining robust functionality even in acidic environments and preventing denaturation in a pH 1 electrolyte. The cobalt porphyrin core of SacCoMyo reduces the activation overpotential for hydrogen generation. A high turnover frequency of about 2400 H2 s-1 is demonstrated in the presence of molecular oxygen, showcasing its potential in biohydrogen production and its ability to overcome the limitations associated with natural hydrogenases.

Abstract
This perspective analyzes recent advances in the spectroelectrochemical investigation of redox proteins and enzymes immobilized on biocompatible or biomimetic electrode surfaces. Specifically, the article highlights new insights obtained by surface-enhanced resonance Raman (SERR), surface-enhanced infrared absorption (SEIRA), protein film infrared electrochemistry (PFIRE), polarization modulation infrared reflection-absorption spectroscopy (PMIRRAS), Förster resonance energy transfer (FRET), X-ray absorption spectroscopy (XAS), electron paramagnetic resonance (EPR), and differential electrochemical mass spectrometry (DMES)-based spectroelectrochemical methods on the structure, orientation, dynamics, and reaction mechanisms for a variety of immobilized species. This includes small heme and copper electron shuttling proteins, large respiratory complexes, hydrogenases, multicopper oxidases, alcohol dehydrogenases, endonucleases, NO-reductases, and dye decolorizing peroxidases, among other enzymes. Finally, I discuss the challenges and foreseeable future developments toward a better understanding of the functioning of these complex macromolecules and their exploitation in technological devices.

Abstract
The ever-increasing demands for clean and sustainable energy sources combined with rapid advances in biointegrated portable or implantable electronic devices have stimulated intensive research activities in enzymatic (bio)fuel cells (EFCs). The use of renewable biocatalysts, the utilization of abundant green, safe, and high energy density fuels, together with the capability of working at modest and biocompatible conditions make EFCs promising as next generation alternative power sources. However, the main challenges (low energy density, relatively low power density, poor operational stability, and limited voltage output) hinder future applications of EFCs. This review aims at exploring the underlying mechanism of EFCs and providing possible practical strategies, methodologies and insights to tackle these issues. First, this review summarizes approaches in achieving high energy densities in EFCs, particularly, employing enzyme cascades for the deep/complete oxidation of fuels. Second, strategies for increasing power densities in EFCs, including increasing enzyme activities, facilitating electron transfers, employing nanomaterials, and designing more efficient enzyme-electrode interfaces, are described. The potential of EFCs/(super)capacitor combination is discussed. Third, the review evaluates a range of strategies for improving the stability of EFCs, including the use of different enzyme immobilization approaches, tuning enzyme properties, designing protective matrixes, and using microbial surface displaying enzymes. Fourth, approaches for the improvement of the cell voltage of EFCs are highlighted. Finally, future developments and a prospective on EFCs are envisioned.

Abstract
Resistance to aminoglycoside antibiotics occurs primarily as a result of aminoglycoside-modification enzymes (AMEs) that modify the antibiotics. In this work, a novel strategy to combat the effects of antibiotic resistance was developed by screening multiple AMEs inhibitors with ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UHPLC-QTOF MS). The method screened inhibitors of three AMEs (AAC(6')-APH(2"), AAC(6') and APH(2")) simultaneously through measuring the acetyltransferase activity and phosphotransferase activity of AAC(6')-APH(2") enzyme in a single assay. Screening inhibitors of multiple targets could greatly improve the screening efficiency at early-stages of drug discovery. In this study, enzyme reaction conditions including cosubstrate, enzyme concentration and cosubstrate concentration were optimized. The inhibition constants (Ki) for two known inhibitors, paromomycin and quercetin, were determined to be 1.23 and 20.27 μM, respectively. The assay was further validated through the determination of a high Z' factor value of 0.73. The developed assay was applied to screen a chemical library against bifunctional AAC(6')-APH(2'') enzyme. Using this assay, two pyrimidinyl indole derivatives were found to be potent, and effective AAC(6')-APH(2'') inhibitors. The assay of exploring the selective inhibitory effect on two AAC(6')-APH(2'') active sites was further performed. Two pyrimidinyl indole derivatives were found to exhibit striking inhibitory activities on AAC(6').
