Yatalase is an enzyme commonly used for filamentous fungi cell wall digestion, enabling protoplast preparation. The product is prepared from cell-culture supernatants of Corynebacterium sp. OZ-21 and consists mainly of chitinase, chitobiase, and beta-1,3-glucanase.
- Can be used to prepare protoplasts from filamentous fungi
- Excellent thermostability at room temperature
- Efficiently digests native chitin
- Cell-wall digestion of filamentous fungi
Corynebacterium sp. OZ-21
Lyophilized preparation is stable for at least 1 year at 4°C.
