Artificial Nanometalloenzyme for Cooperative Tandem Catalysis.

08:00 EDT 15th April 2019 | BioPortfolio

Summary of "Artificial Nanometalloenzyme for Cooperative Tandem Catalysis."

Artificial metalloenzymes which combine the advantages of natural enzymes and metal catalysts have been getting more research attention. As a proof of concept, an artificial nanometalloenzyme (CALB-Shvo@MiMBN) was prepared by co-encapsulation of metallo-organic catalyst and enzyme in a soft nanocomposite consisting of 2-methylimidazole, metal ion, and biosurfactant in mild reaction conditions using one-pot self-assembly method. The artificial nanometalloenzyme with lipase acted as the core and metallo-organic catalyst embedded in micropore exhibited a spherical structure of 30-50 nm in diameter. The artificial nanometalloenzyme showed high catalytic efficiency in dynamic kinetic resolution of racemic primary amines or secondary alcohols, compared to one-pot catalytic reaction of immobilized lipase and free metallo-organic catalyst. This artificial nanometalloenzyme holds great promise for integrated enzymatic and heterogeneous catalysis.

Medical and Biotech [MESH] Definitions

Copies of DNA sequences which lie adjacent to each other in the same orientation (direct tandem repeats) or in the opposite direction to each other (INVERTED TANDEM REPEATS).

A variety of simple di- (DINUCLEOTIDE REPEATS), tri- (TRINUCLEOTIDE REPEATS), tetra-, and pentanucleotide tandem repeats (usually less than 100 bases long). They are dispersed in the euchromatic arms of most chromosomes. They are also known as short tandem repeats (STRs).

The most common of the microsatellite tandem repeats (MICROSATELLITE REPEATS) dispersed in the euchromatic arms of chromosomes. They consist of two nucleotides repeated in tandem; guanine and thymine, (GT)n, is the most frequently seen.

Potassium channels that contain two pores in tandem. They are responsible for baseline or leak currents and may be the most numerous of all K channels.

Devices intended to replace non-functioning organs. They may be temporary or permanent. Since they are intended always to function as the natural organs they are replacing, they should be differentiated from PROSTHESES AND IMPLANTS and specific types of prostheses which, though also replacements for body parts, are frequently cosmetic (EYE, ARTIFICIAL) as well as functional (ARTIFICIAL LIMBS).
