Tailoring recombinant lipases: keeping the His-tag favors esterification reactions, removing it favors hydrolysis reactions. Sci Rep 2018; 8:10000. [PMID: 29968752 PMCID: PMC6030132 DOI: 10.1038/s41598-018-27579-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2017] [Accepted: 06/04/2018] [Indexed: 12/19/2022] Open
Abstract
We determined the effect of the His-tag on the structure, activity, stability and immobilization of LipC12, a highly active lipase from a metagenomic library. We purified LipC12 with a N-terminal His-tag and then removed the tag using tobacco etch virus (TEV) protease. Circular dichroism analysis showed that the overall structure of LipC12 was largely unaffected by His-tag removal. The specific hydrolytic activities against natural and artificial substrates were significantly increased by the removal of the His-tag. On the other hand, His-tagged LipC12 was significantly more active and stable in the presence of polar organic solvents than untagged LipC12. The immobilization efficiency on Immobead 150 was 100% for both forms of LipC12 and protein desorption studies confirmed that the His-tag does not participate in the covalent binding of the enzyme. In the case of immobilized LipC12, the His-tag negatively influenced the hydrolytic activity, as it had for the free lipase, however, it positively influenced the esterification activity. These results raise the possibility of tailoring recombinant lipases for different applications, where the His-tag may be retained or removed, as appropriate for the desired activity.

Kinetic behaviour of recombinant Fusarium solani lipases using monomolecular films: Effect of the heterologous expression. Int J Biol Macromol 2016; 94:319-325.

Abstract
Two lipases from Fusarium solani, FSL and FSL2, were efficiently expressed in Pichia pastoris. To check the influence of the expression on interfacial properties of FSL and to study kinetic properties of FSL2, interfacial parameters of FSL2, native FSL, untagged recombinant and tagged recombinant forms of FSL were compared using the monomolecular film technique. Kinetic study on the dependence of the stereoselectivity of these lipases on the surface pressure was performed using three dicaprin isomers spread in the form of monomolecular films at the air-water interface. The FSL2 seems to have an important penetration power with a preference for adjacent ester groups and the heterologous expression accompanied or not with the N-His-tag extension on the FSL were found to modify the pressure preference and increase the catalytic hydrolysis rate of three dicaprin isomers. The heterologous expression was found to preserve the FSL regioselectivity without affecting its stereospecificity at high and low surface pressure. The evaluation of the recombinant expression Effects on Catalysis (REC), the N-Tag Effects on Catalysis (TEC), and the N-Tag and Recombinant expression Effects on Catalysis (TREC) showed that the heterologous expression was more efficient than the presence of the N-terminal tag extension on the FSL.
