Product Specs

Introduction

Lipase, classified as EC 3.1.1.3, is an enzyme found widely in nature that breaks down fats and oils. The lipase derived from Serratia marcescens is known for its ability to selectively produce specific mirror-image forms of molecules. It does this particularly well in a process called biocatalytic hydrolysis, where it acts on a compound called trans-3-(4-methoxyphynyl) glycidic acid methyl ester [(±)-MPGM]. This process results in the production of a specific form called (2R, 3S)-3-(4-methoxyphenyl) glycidic acid methyl ester [(-)-MPGM].

Description
Recombinant Immobilized Serratia marcescens Lipase-A, with a molecular weight of 65 kDa, is produced in E. coli bacteria and purified using standard techniques.
Physical Appearance
A sterile, filtered powder that has been freeze-dried.
Formulation
The protein was freeze-dried without any additional substances.
Solubility
To use the freeze-dried Lipase-A, it is recommended to dissolve it in a sterile solution of 10%-50% DMSO, isopropyl ether, petroleum ether, ethanol, acetone, or isopropanol.
Stability
While Recombinant Lipase-A remains stable at room temperature for a week, it is best stored in a dry state below -18°C. For extended storage, adding a carrier protein (0.1% HSA or BSA) is advised. Avoid repeated freezing and thawing.
Application Stability
The enzyme is active within a pH range of 5 to 10 and is unstable above 50°C. It exhibits higher activity in solutions containing 10%-50% DMSO, isopropyl ether, petroleum ether, 10%-25% ethanol, acetone, or isopropanol. While it maintains 50% activity in 50% acetone and isopropanol, it shows no activity in 50% ethanol.
Purity
SDS-PAGE analysis shows a purity greater than 90%.
Unit Definition
The activity of Lipase-A is measured using a substance called p-nitrophenyl acetate (pNPA). One unit of lipase activity is defined as the amount of enzyme that releases 1.0 µmol of p-nitrophenol every minute.
Biological Activity
The biological activity is measured as 580 units per milligram of powder.
Source

Product Science Overview

Introduction

Lipases are enzymes that catalyze the hydrolysis of fats into glycerol and free fatty acids. They are widely used in various industrial applications, including the production of biodiesel, food processing, pharmaceuticals, and detergents. Recombinant lipases, such as Lipase-A Recombinant, are produced using genetic engineering techniques to enhance their properties and production efficiency.

Production of Recombinant Lipases

Recombinant lipases are produced by inserting the gene encoding the lipase enzyme into a suitable host organism. Common hosts for recombinant lipase production include Escherichia coli and Komagataella phaffii (previously known as Pichia pastoris) . These hosts are chosen for their ability to produce high yields of the enzyme and their ease of genetic manipulation.

The production process involves several steps:

  1. Gene Cloning: The gene encoding the lipase enzyme is isolated and inserted into a plasmid vector.
  2. Transformation: The plasmid vector is introduced into the host organism, which then expresses the lipase gene.
  3. Fermentation: The host organism is cultured in a bioreactor under optimal conditions to produce the lipase enzyme.
  4. Purification: The lipase enzyme is purified from the culture medium using various techniques such as chromatography.
Engineering and Immobilization

To improve the properties of recombinant lipases, protein engineering techniques such as rational design and directed evolution are employed . These techniques allow scientists to modify the enzyme’s structure to enhance its stability, activity, and specificity.

Additionally, recombinant lipases can be immobilized on various supports to improve their properties and enable their reuse . Immobilization techniques include adsorption, covalent binding, and entrapment. Immobilized lipases are particularly useful in industrial applications where enzyme reuse and stability are critical.

Applications

Recombinant lipases have a wide range of applications in various industries :

  • Pharmaceuticals: Lipases are used in the synthesis of enantiopure drugs, which are important for producing medications with specific therapeutic effects.
  • Food Processing: Lipases are used in the production of flavors, fragrances, and emulsifiers.
  • Biodiesel Production: Lipases catalyze the transesterification of triglycerides to produce biodiesel, a renewable and environmentally friendly fuel.
  • Detergents: Lipases are used in laundry detergents to break down fats and oils, improving the cleaning efficiency.
