설명

애플리케이션

Lyticase from Arthrobacter luteus has been used to lyse the fungal cell wall for DNA isolation.[1][2][3]

Lyticase from Arthrobacter luteus has been used:

• for spheroplasting the cells
• as a component of digestion solution to incubate yeast cells for digestion of the cell wall
• in the enzymatic hydrolysis of the mycelium precipitate to prepare protoplasts

생화학적/생리학적 작용

Lyticase enzyme is frequently used in fungal research, particularly for species identification using polymerase chain reaction (PCR)-based techniques. It can break down β (1→3) and β (1→4) bonds between glucose units. Lysozyme serves as an indicator of macrophage-mediated host response, correlates with white cell death, and exhibits a high turnover rate. Elevated levels of serum lysozyme have been observed in various chronic inflammatory conditions, inflammatory bowel diseases, hematological disorders, and renal disorders. The c-type lysozyme from hen egg white is commonly used as a model for studying protein structure and function. Muramidase primarily exhibits bactericidal activity against Gram-positive bacteria. The method described in the bulletin for determining molecular masses using gel filtration chromatography is a modified version of existing published techniques. The protein standards included in this kit may be compatible with other chromatographic systems like high-performance liquid chromatography (HPLC). However, certain buffer systems may affect the elution volumes of albumin and carbonic anhydrase. The proteins in this kit have a molecular mass range spanning from 29 kDa to 699 kDa.

Lyticase hydrolyzes poly-β(1→3)-glucose such as yeast cell wall glucan.

Yeast cells are difficult to disrupt because the cell walls may form capsules or resistant spores. DNA can be extracted from yeast by using lysing enzymes such as lyticase to induce partial spheroplast formation.[4] Spheroplasts are subsequently lysed to release DNA. Lyticase is preferred to digest the cell walls of yeast and generate spheroplasts from fungi for transformation. It contains β-(1→3)-glucan laminaripentaohydrolase along with β-(1→3)-glucanase, protease, and mannanase activities.[5] Lyticase is used for yeast cells like Candida, Debaryomyces, Saccharomyces, Saccharomycopsis, Saccharomycodes, Eremothecium, and Schwanniomyces species.[6]
