Puriflcation and properties of chitin deacetylase from Absidiaorchidis
Methods of purification of chitin deacetylase are discussed. A two stepmethod of purification of chitin deacetylase from mycelial extracts ofthe fungusAbsidia orchidis by chromatography is presented. The crude enzyme extract waspurified by a gel chromatography and then by ion exchange chromatography.Specific activity of purified enzyme was 12.3 U/mg and final purification degreewas 147. The apparent molecular mass of the enzyme was 75 kDa. When 0 -hydroxyethylated chitin (glycol chitin) was used as a substrate, the optimum pHfor enzyme activity was 5,5 and the optimum temperature was 50°C
