General description
Die enzymatische Hydrolyse von Chitin zu N-Acetyl-D-glucosamin beinhaltet zwei aufeinanderfolgende Enzymreaktionen:
- Die erste Reaktion, Chitodextrinase-chitinase, ist eine Poly(β-(1→4)-[2-acetamido-2-desoxy-D-glucosid])-glycanohydrolase, mit der Chitobioseeinheiten aus Chitin entfernt werden.
- Die zweite Reaktion ist eine N-Acetyl-glucosaminidase-chitobiase, welche das Disaccharid in seine Monomeruntereinheiten (N-Acetyl-D-glucosamin) spaltet.
Application
Im Gesundheitswesen: Asthma
Im Pharmabereich: Herstellung von Chitooligosacchariden und N-Acetyl-D-glucosamin
Herstellung von Einzelzellprotein
Isolation von Protoplasten aus Pilzen und Hefe
Bekämpfung pathogener Pilze
Behandlung von Chitinabfällen, Bekämpfung von Stechmücken und Morphogenese

How many U/ml of Chitinase are recommended to use for fungal DNA extraction?
1 answer-
The optimal recommended units of chitinase per milliliter (U/mL) for fungal DNA extraction vary depending on the protocol and fungal species employed. For protocol and working concentration reference, a relevant citation is available in Fungal Biology and Biotechnology 12.1 (2025): 1-17.

The Chitinase is provided based on units of activity, and the protein mass will vary for individual lots. The specification states that the specific activity will be ≥ 50.00 units per mg protein. The specification sheet can be found here:
https://www.sigmaaldrich.com/specification-sheets/176/740/C9830-10UN________SIGMA____.pdfThe Data Sheet provides the following reconstitution instructions:
Prepare a stock solution by reconstituting a 10 unit vial with 300 ul of water. For long term solution storage reconstitute vial with 50% glycerol solution.
