Activity Measurement of Chitosanase by an Amperometric Biosensor [PDF]
An amperometric biosensor for the detection of glucosamine (GlcN) and chitosan oligosaccharides ((GlcN)n) was introduced for an activity measurement of chitosanase. By using the biosensor, an increase in the anodic current due to the production of GlcN and (GlcN)n by chitosanase was measured in a chitosan solution. The maximum value of the slope of the

Structural simulation and protein engineering to convert an endo-chitosanase to an exo-chitosanase [PDF]
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
