LITERATURE

acetone, n-butanol and ethylacetate rapidly denature the enzyme

Bacillus sp. (in: Bacteria)

-

646772

heat treatment leads at a concentration of 0.0106 mM protein at 75°C to a irreversible unfolding, but this is reversible when the protein concentation is 20 times lower

Bacillus subtilis

-

646775

quite stable in 5% SDS

Bacillus sp. (in: Bacteria)

-

646771

resistant to 6 M urea or 2 M guanidine HCl at 37°C for 30 min

Bacillus sp. (in: Bacteria)

-

646771

the enzyme retaines 70% activity after incubation with 10 M urea at room temperature for 30 min

Aspergillus fumigatus
