High-level expression and characterization of a highly thermostable chitosanase from Aspergillus fumigatus in Pichia pastoris.
Biotechnol. Lett. 34(4) , 689-94, (2012) The sequence of an endo-chitosanase gene (CSN) from Aspergillus fumigatus was optimized based on the preferred codons of Pichia pastoris and synthesized in vitro through overlapping PCR (CSN-P). The gene was cloned into a yeast expression vector, pHBM905A, an... |

Preparation of D-glucosamine by hydrolysis of chitosan with chitosanase and β-D-glucosaminidase.
Int. J. Biol. Macromol. 61 , 160-3, (2013) Crude enzymes including chitosanase and β-D-glucosaminidase were obtained by centrifugal separation from the fermentation broth of Microbacterium sp. OU01. Then the crude enzymes are used to hydrolyze chitosan for producing D-glucosamine (GlcN). The effects o... |

Classification of chitosanases by hydrolytic specificity toward N¹,N⁴-diacetylchitohexaose.
Biosci. Biotechnol. Biochem. 76(10) , 1932-7, (2012) The hydrolytic specificities of chitosanases were determined using N¹,N⁴-diacetylchitohexaose [(GlcN)₂-GlcNAc-(GlcN)₂-GlcNAc]. The results for the hydrolytic specificities of chitosanases belonging to subclasses I, II, and III toward chitohexaose and N¹,N⁴-di... |

Cloning and characterization of a gene coding for a major extracellular chitosanase from the koji mold Aspergillus oryzae.
Biosci. Biotechnol. Biochem. 76(1) , 193-5, (2012) A gene coding for a major extracellular chitosanase was isolated from Aspergillus oryzae IAM2660. It had a multi-domain structure composed of a signal peptide, a catalytic domain, Thr- and Pro-rich linkers, and repeated peptides (the R3 domain) from the N-ter... |

Characterization of antifungal activity of the GH-46 subclass III chitosanase from Bacillus circulans MH-K1.
Antonie van Leeuwenhoek 104(5) , 737-48, (2013) We characterized the antifungal activity of the Bacillus circulans subclass III MH-K1 chitosanase (MH-K1 chitosanase), which is one of the most intensively studied glycoside hydrolases (GHs) that belong to GH family 46. MH-K1 chitosanase inhibited the growth ... |
