Application
Lyticase from Arthrobacter luteus has been used for resuspending cells to extract high-molecular weight DNA for polymerase chain reaction (PCR) fingerprint analyses.
Lyticase from Arthrobacter luteus has been used:
- as a component in spheroplasting buffer to prepare yeast nuclear extracts
- for digestion in sample preparation for β-glucan enzymatic assay using yeast
- to lyse cells for RNA isolation
Biochem/physiol Actions
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.
Lyticase is a lysing enzyme that is used to extract DNA from yeast cells by inducing partial spheroplast formation. Spheroplasts are subsequently lysed to release DNA. Lyticase is preferred to digest cell walls of yeast, which are difficult to disrupt because the cell walls may form capsules or resistant spores. Lyticase contains β-(1→;3)-glucan laminaripentaohydrolase along with β-(1→3)-glucanase, protease, and mannanase activities. It is useful with yeast cells such as e.g. Candida, Debaryomyces, Saccharomyces, Saccharomycopsis, Saccharomycodes, Eremothecium, and Schwanniomyces species.
Lyticase hydrolyzes poly-β(1→3)-glucose such as yeast cell wall glucan.
Unit Definition
One unit will produce a ΔA800 of 0.001 per min at pH 7.5 at 25 °C, using a suspension of yeast as substrate in a 3 mL reaction mixture.
