Calcium triggers the refolding of Bacillus subtilis chitosanase [PDF]
Biochemical Journal, 2003 We characterized the reversible folding—unfolding transition of Bacillus subtilis exocellular chitosanase from either thermal or urea denaturation of the protein. The transitions were monitored in each case by intrinsic fluorescence changes and resistance to proteolysis.
