Structural simulation and protein engineering to convert an endo-chitosanase to an exo-chitosanase [PDF]
Protein Engineering Design and Selection, 2008 To obtain an enzyme for the production of chito-disaccharides (GlcN(2)) by converting endo-chitosanase to exo-chitosanase, we chose an endo-chitosanase from Bacillus circulans MH-K1 (Csn) as the candidate for protein engineering. Using molecular modeling, two peptides with five amino acids (PCLGG) and six amino acids (SRTCKP) were designed and inserted

Reassessment of chitosanase substrate specificities and classification [PDF]
Nature Communications, 2017 AbstractChitosanases can be used to produce partially acetylated chitosan oligosaccharides (paCOS) for different applications, provided they are thoroughly characterized. However, recent studies indicate that the established classification system for chitosanases is too simplistic.
