[PMID: 33926034 PMCID: PMC8123588 DOI: 10.3390/s21093038] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 04/13/2021] [Accepted: 04/15/2021] [Indexed: 12/23/2022]
Abstract
Enzymatic biosensors enjoy commercial success and are the subject of continued research efforts to widen their range of practical application. For these biosensors to reach their full potential, their selectivity challenges need to be addressed by comprehensive, solid approaches. This review discusses the status of enzymatic biosensors in achieving accurate and selective measurements via direct biocatalytic and inhibition-based detection, with a focus on electrochemical enzyme biosensors. Examples of practical solutions for tackling the activity and selectivity problems and preventing interferences from co-existing electroactive compounds in the samples are provided such as the use of permselective membranes, sentinel sensors and coupled multi-enzyme systems. The effect of activators, inhibitors or enzymatic substrates are also addressed by coupled enzymatic reactions and multi-sensor arrays combined with data interpretation via chemometrics. In addition to these more traditional approaches, the review discusses some ingenious recent approaches, detailing also on possible solutions involving the use of nanomaterials to ensuring the biosensors' selectivity. Overall, the examples presented illustrate the various tools available when developing enzyme biosensors for new applications and stress the necessity to more comprehensively investigate their selectivity and validate the biosensors versus standard analytical methods.

Abstract
Alcohol oxidase (EC 1.1.3.13; AOX) is a flavoprotein that catalyzes the oxidation of primary short-chain alcohols to corresponding carbonyl compounds with a concomitant release of hydrogen peroxide. It is a key enzyme of methanol metabolism in methylotrophic yeasts, catalyzing the first step of methanol oxidation to formaldehyde.Here we describe the isolation and purification of AOX from the thermotolerant methylotrophic yeast Ogataea (Hansenula) polymorpha, and using this enzyme in enzymatic assay of ethanol, simultaneous analysis of methanol and formaldehyde, and in construction of amperometric biosensors selective to primary alcohols and formaldehyde.

Abstract
Novel nanomaterials, including metallic nanoparticles obtained via green synthesis (gNPs), have a great potential for application in biotechnology, industry and medicine. The special role of gNPs is related to antibacterial agents, fluorescent markers and carriers for drug delivery. However, application of gNPs for construction of amperometric biosensors (ABSs) is not well documented. The aim of the current research was to study potential advantages of using gNPs in biosensorics. The extracellular metabolites of the yeast Ogataea polymorpha were used as reducing agents for obtaining gNPs from the corresponding inorganic ions. Several gNPs were synthesized, characterized and tested as enzyme carriers on the surface of graphite electrodes (GEs). The most effective were Pd-based gNPs (gPdNPs), and these were studied further and applied for construction of laccase- and alcohol oxidase (AO)-based ABSs. AO/GE, AO-gPdNPs/GE, laccase/GE and laccase-gPdNPs/GE were obtained, and their analytical characteristics were studied. Both gPdNPs-modified ABSs were found to have broader linear ranges and higher storage stabilities than control electrodes, although they are less sensitive toward corresponding substrates. We thus conclude that gPdNPs may be promising for construction of ABSs for enzymes with very high affinities to their substrates.

Abstract
Alcohol oxidase (AOX) functions in oxidation of primary alcohols into the corresponding aldehydes with potential on catalyzing synthesis reactions in chemical industry. In this study, AOX from a thermotolerant methylotrophic yeast, Ogataea thermomethanolica (OthAOX) was purified to high homogeneity using a single step chromatographic separation on a DEAE-Sepharose column. The purified OthAOX had a specific activity of 15.34 U/mg with 77.5% recovery yield. The enzyme worked optimally at 50 °C in an alkaline range (pH 9.0). According to kinetic analysis, OthAOX showed a higher affinity toward short-chain aliphatic primary alcohol with the Vmax, Km, and kcat of 0.24 nmol/min, 0.27 mM, and 3628.8 min-1, respectively against methanol. Addition of alginic acid (0.35%) showed a protective effect on enhancing thermal stability of the enzyme, resulting in 72% increase in its half-life at 40 °C under the operational conditions. This enzyme represents a promising candidate for conversion of bioethanol to acetaldehyde as secondary chemical in biorefinery.

Abstract
The genetic transformation of target cells is a key tool in modern biological research, as well as in many gene therapy and biotechnology applications. Here we describe a new method for delivery of DNA into several industrially important species of yeast, including Saccharomyces cerevisiae. Our method is based on the use of a novel nanoscale oligoelectrolyte polymer possessing a comb-like structure as a carrier molecule. Direct comparisons to standard transformation methods clearly show that our approach: (i) yields two times more transformants of Hansenula polymorpha NCYC 495 compared to electroporation approaches and 15 times more transformants compared to lithium acetate protocols, as well as (ii) 5 times more Pichia pastoris GS115 transformants compared to electroporation and 79 times more transformants compared to lithium acetate. Taken together, these results clearly indicate genetic transformation of yeasts using oligoelectrolyte polymer carriers is a highly effective means of gene delivery.

Abstract
Alcohol oxidase (AO) was extracted from the methylotrophic yeast Pichia putida and purified using various methods. AO purified by crystallization was homogeneous based on analytical centrifugation with subsequent gel filtration and SDS-PAGE. The molecular weight of the enzyme was around 600 kDa. SDS-PAGE revealed a single protein band (74 +/- 4 kDa), and 8-9 bands of native protein with similar specific AO activities and substrate specificities were identified by PAGE without SDS. Electron microscopy of a single molecule revealed eight subunits located on the top of a regular tetragon with dotted symmetry of 422 D4 providing evidence that AO consists of eight subunits. Apparently, each molecule of AO has two types of subunits with very similar molecular weights and differing from each other by the number of acidic and basic amino acid residues. Each subunit includes one molecule of FAD and 2-3 cysteine residues. The pH optimum was within 8.5-9.0. Specific activity of the enzyme varied from 10 to 50 micromol methanol/min per mg protein from batch to batch depending on separation methods and had linear relationship with protein concentration. The AO was quickly inactivated at 20 degrees C and seemed to be stable in phosphate-citrate buffer with 30-50% (w/v) of sucrose. Different forms of 0.1-1 mm crystals of the enzyme were obtained. However the crystals did not yield X-ray reflections, apparently as a result of their molecular microheterogeneity.

Abstract
Methods for colony assay of peroxisomal oxidases in yeasts provide a convenient and fast approach for monitoring peroxisome status. They have been used in several laboratories for the isolation of yeast mutants deficient in selective autophagic peroxisome degradation (pexophagy), catabolite repression of peroxisomal enzymes or mutants deficient in oxidases themselves. In this chapter, protocols for monitoring peroxisomal alcohol oxidase and amine oxidase directly in yeast colonies and examples of their application for mutant isolation are described. These methods were successfully utilized in several methylotrophic yeasts and the alkane-utilizing yeast Yarrowia lipolytica.
