Mainly, the ongoing researches focus on the improvements of kinetic and enzymatic characteristics of enzymes to meet industrial needs. With the discovery of psychrophilic cellulase and lipase sources, a new era has opened for protein research by allowing the discovery of novel functions together with the description of unique cold adaptation mechanisms to harsh environments. The ability of cold-adapted lipase and cellulases to enable chemical reactions at lower temperatures provides a great opportunity to cut the cost of the finished product by lowering energy and purifying expanses. The advances in the cold-adapted lipase and cellulase enzymes are the cumulative efforts of organic chemists, biophysicists, biotechnologists, and process engineers who greatly contribute to a better understanding of cold-adaptation phenomena from different points of view. In this review, we cover the cold-adaptation aspects of cellulase and lipase enzymes from structural points of view by referring to the roles of Gly and Pro residues. Gly and Pro residues accelerate the cold-adaptation of enzymes by altering the conformational changes in the 3 D structure of proteins The list of microorganisms as a source of cold-adapted cellulases and lipases is given by referring to biotechnological applications. After introducing the thermodynamic background of Gly and Pro residues in the phenomena of cold-adaptation, specific examples are given to emphasise how introducing Gly and Pro into 3 D structure of protein molecules adds value in terms of biotechnological application by contributing to cold-adaptation.","PeriodicalId":8824,"journal":{"name":"Biocatalysis and Biotransformation","volume":"41 1","pages":"243 - 260"},"PeriodicalIF":1.8,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49133235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laccase was found to be active only in a low amount of choline chloride containing NADESs while it maintained its activity both in high and low amounts of betaine containing NADESs. Rutin, as a flavonoid monomer shows high antioxidant, antibacterial, antiviral and anti-inflammatory properties and these properties are enhanced in the polymerised form. In this study, the organic co-solvent that is conventionally used in the oligomerization of rutin was replaced with two different green solvents, choline chloride-ethylene glycol (1:2 molar ratio) and betaine-mannose (5:2 molar ratio). LC-MS results revealed spontaneous derivatization of rutin as well as the oligomerization of the derivatives besides rutin. The final products were found to have enhanced superoxide radical activity. In this study, enzymatic oligomerization of rutin was investigated for the first time in the presence of eco-friendly green solvents presenting an alternative pathway without any toxic components.","PeriodicalId":8824,"journal":{"name":"Biocatalysis and Biotransformation","volume":"41 1","pages":"353 - 366"},"PeriodicalIF":1.8,"publicationDate":"2022-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47322910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The global enzyme market size is predicted to expand at a CAGR of 6.5% from 2021 to 2028. Enzymatic reactions are highly chemo, regio, and stereoselective and produce various fine chemicals such as drugs, agrochemicals, and fragrance molecules. Peroxidases (PO) (EC 1.11.1.x) are a large class of enzymes that play an important role in various biological processes. Chloroperoxidase (CPO, EC 1.1.1.10) is a versatile fungal haem-thiolate protein that is useful in the asymmetric synthesis of chiral building blocks and has an important role in a number of biological processes. CPO’s main biological role is chlorination, although it also catalyses haem PO, catalase (CAT), and reactions similar to cytochrome P450. However, CPO performs both oxidation and stereo-specific halogenation of chemical molecules. The haem and vanadium POs are produced by Caldariomyces fumago, and Curvularia inaequalis, respectively, and are capable of halogenating the flavanones, naringenin, and hesperetin, at C-6 and C-8 in the presence of either Cl− or Br−. In this review, we discussed the various applications of CPO including synthesis of epoxides, drugs, halogenation of thymol, nitriles, the Aza-Achmatowicz reaction, and biomedical applications such as cancer and biosensors. In light of these novel features, we have provided a detailed review of CPOs and their applications in various stereoselective chemical transformations of industrial relevance.","PeriodicalId":8824,"journal":{"name":"Biocatalysis and Biotransformation","volume":"41 1","pages":"403 - 420"},"PeriodicalIF":1.8,"publicationDate":"2022-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47184745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
