[PMID: 37992944 DOI: 10.1016/j.ijbiomac.2023.128302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 11/14/2023] [Accepted: 11/19/2023] [Indexed: 11/24/2023]
Abstract
Structure-guided bioengineering enzymes has been an efficient strategy to obtain biocatalyst with desirable properties. In this study, the cold-adapted esterase from Pseudomonas sp. (CPE) was optimized through bioinformatic-based structured-guided bioengineering on lid1 region. Substitutions of non-conserved Q55 led to noticeable increase in hydrolysis without sacrificing enzyme thermostability, activating effects of Ca2+ and organic solvents. Compared to the wild type, both of Q55V and Q55N among the constructed variants exhibited about a 2.0-fold and 6.5-fold higher hydrolytic activity toward short-chain and long-chain substrates, respectively. In contrast, lid swapping with the lid of Thermomyces lanuginosus lipase reduced the activity and thermostability of CPE. Catalytic kinetics revealed that substitution of Q55 with Y, V, N and R enhanced the substrate affinity of CPE. Hydrolysis by Q55V remarkedly enriched the characteristic flavor components of single cream. The study sheds light on structure-guided bioengineering of lid tailoring cold-adapted esterases with desired catalytic performance to meet the demand from biotechnological applications.

Abstract
The applications of lipases in esterification, amidation, and transesterification have broadened their potential in the production of fine compounds with high cumulative values. Mostly, the catalytic triad of lipases is covered by either one or two mobile peptides called the "lid" that control the substrate channel to the catalytic center. The lid holds unique conformational allostery via interfacial activation to regulate the dynamics and catalytic functions of lipases, thereby highlighting its importance in redesigning these enzymes for industrial applications. The structural characteristic of lipase, the dynamics of lids, and the roles of lid in lipase catalysis were summarized, providing opportunities for rebuilding lid region by biotechniques (e.g., metagenomic technology and protein engineering) and enzyme immobilization. The review focused on the advantages and disadvantages of strategies rebuilding the lid region. The main shortcomings of biotechnologies on lid rebuilding were discussed such as negative effects on lipase (e.g., a decrease of activity). Additionally, the main shortcomings (e.g., enzyme desorption at high temperatre) in immobilization on hydrophobic supports via interfacial action were presented. Solutions to the mentioned problems were proposed by combinations of computational design with biotechnologies, and improvements of lipase immobilization (e.g., immobilization protocols and support design). Finally, the review provides future perspectives about designing hyperfunctional lipases as biocatalysts in the food industry based on lid conformation and dynamics.

Abstract
Lipases are important enzymes in many biochemical industries, thus making them attractive targets for protein engineering to improve enzymatic properties. In this work, a ''reverse engineering'' approach was explored: disrupt secondary structures to determine their contribution to enzyme stability and activity. All the α-helices of the lipase from Pseudomonas aeruginosa PAO1 (PAL) were systematically disrupted using computational proline mutagenesis and molecular dynamics (MD) simulations. This method identified the α3 mutant (R89P), located within the vicinity of the active site, to be significantly important for stability and activity. In addition, the α6 system (L159P), part of the ''cap'' domain that regulates substrate entry into the active site, was found to be critical for activity as it pushed the lipase to adopt a completely closed conformation. The perturbation introduced by the proline mutations resulted in increased backbone flexibility that significantly decreased protein stability. Moreover, mutations within the cap domain helices - α4 (A115P), α5 (S132P, G139P), α6 (L159P), and α7 (R169P) - resulted in increased flexibility of the N-terminal region of the α5 helix, the mobile ''lid'' helix, that pushes the gorge into a partially closed conformation. The α6 mutation (L159P) further increased the flexibility of the helix-loop region at the C-terminal end of the α5 helix to push the lid into the fully closed state. Therefore, the α3 and α6 helices could be ''hot spots'' for stabilizing mutations that could improve the overall enzyme stability and activity this lipase. The insights obtained in this work may be validated experimentally in future works.

Abstract
BACKGROUND Both high pressure and environmental factors could influence the catalytic abilities of enzymes. This work investigated coupled effects of pressure and salts on Rhizopus chinensis lipase (RCL) to provide significant information for its further applications. RESULTS The maximum activity of RCL was observed under 200 MPa at 40 °C. The highest activity was achieved at concentrations of 0.06-0.1 mol L-1 for tested salts. The effect of monovalent cations on RCL activity followed the Hofmeister series (K+ > Na+ > Li+ ) at 0.1 MPa but the order of Na+ and K+ was changed under 200 MPa. Meanwhile, the effects of anions did not follow the Hofmeister series. KCl slightly improved the thermostability of RCL at moderate concentration. At 60 °C, LiCl only stabilised RCL at 0.1 mol L-1 . The pre-transition unfolding point was shifted from 4.5 to 3.5 mol L-1 with pressure increasing from 0.1 to 600 MPa. In addition, KCl could not change the lipase's extrinsic fluorescence evolution versus pressure. CONCLUSION Pressure and salts could improve catalytic ability and stability of RCL under appropriate conditions. The effect of high pressure on RCL was influenced by salts. Meanwhile salts cannot prevent high pressure-induced damage to RCL. © 2017 Society of Chemical Industry.

Abstract
Lipases are important industrial enzymes. Most of the lipases operate at lipid–water interfaces enabled by a mobile lid domain located over the active site. Lid protects the active site and hence responsible for catalytic activity. In pure aqueous media, the lid is predominantly closed, whereas in the presence of a hydrophobic layer, it is partially opened. Hence, the lid controls the enzyme activity. In the present review, we have classified lipases into different groups based on the structure of lid domains. It has been observed that thermostable lipases contain larger lid domains with two or more helices, whereas mesophilic lipases tend to have smaller lids in the form of a loop or a helix. Recent developments in lipase engineering addressing the lid regions are critically reviewed here. After on, the dramatic changes in substrate selectivity, activity, and thermostability have been reported. Furthermore, improved computational models can now rationalize these observations by relating it to the mobility of the lid domain. In this contribution, we summarized and critically evaluated the most recent developments in experimental and computational research on lipase lids.
