Biochem/physiol Actions

Lyticase is a lysing enzyme that is used to extract DNA from yeast cells by inducing partial spheroplast formation.[3] 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.[4] It is useful with yeast cells such as e.g. Candida,[5] 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.
