EXPRESSION
ORGANISM
UNIPROT
LITERATURE
chitin deacetylase is expressed exclusively during sporulation
-
chitin deacetylase is produced during vegetative growth
-
chitin deacetylase is specifically expressed during fruiting body development
-
commercial wheat bran medium (pH 6.4) supplemented with chitosan favors maximal chitin deacetylase yield
feeding of Bacillus thuringiensis (Bt) diet changes the expression level of isozymes Hacda1, Hacda2, Hacda5a, and Hacda5b significantly and differentially in the third-instar larvae. Hacda2 is suppressed constantly postfeeding on Bt diet
glycerol induces the enzyme by 50%
-
non-ionic surfactants like Tween 40, Tween 60 and Tween 80 increase CDA production, Ca2+ also leads to increased enzyme production in submerged culture
Penicillium oxalicum SAEM-51 is a hyperproducer of chitin deacetylase. Microwave irradiation (10 sec) has about 2fold enhanced level of extracellular but not intracellular enzyme production. Glucose as compared to chitin or colloidal chitin results in increased levels of enzyme production. However, replacement of glucose with chitinous substrates prolonges the duration for enzyme production
the highest yield of enzyme is achieved in a liquid medium containing 2% powder chitin at pH 9.0, 28°C and 150 rpm
total inhibition of CDA production when Ag2+, Co2+, Hg2+, Mn2+ and Ni2+ are added to the medium even at 5 mM concentration, Cu2+ leads to decreased enzyme production in submerged culture
yeast extract at a concentration of 1.0% is an ideal nitrogen source for enzyme production (16.78 EU/ml). Starch at 2% functions best as the major carbon source for optimum enzyme production (17.84 EU/ml). Magnesium sulfate at a concentration of 0.04% is an ideal inorganic salt for enzyme production (17.45 EU/ml). Ideal pH and temperature for optimum enzyme production are pH 6 and 37°C
