摘要： PURPOSE: A novel exochitinase isolated from Pseudoalteromonas issachenkonii is provided to ensure high activity at wide temperature and pH concentration range and to maintain enzyme activity. CONSTITUTION: An exochitinase has an amino acid sequence of sequence number 1. The exochitinase is derived from Pseudoalteromonas issachenkonii KOPRI 22718(KCTC 11415BP). An exochitinase has a nucleotide sequence of sequence number 2. A recombinant vector contains the exochitinase gene. A recombinant microorganism is obtained by inserting exochitinase gene to host cell chromosome or introducing the recombinant vector to a host cell. The exochitinase is obtained by culturing the recombinant microorganism.

摘要： A novel endochitinase and Sanguibacter sp. producing the same endochitinase are provided to show high activity of the endochitinase at various temperature including cool temperature and pH ranges, and stable activity in the presence of surfactants, so that the novel endochitinase and its producing microorganism are useful for production of chitinoligomer from chitin. A gene encoding the novel endochitinase has the nucleotide sequence of SEQ ID NO:1. The Sanguibacter sp. KCTC 10714BP produces the novel endochitinase encoded by the gene of SEQ ID NO:1. The novel endochitinase is produced by (a) culturing Sanguibacter sp. KCTC 10714BP or transformed Escherichia coli containing the endochitinase gene in a medium containing 0.1-1% of chitin as a carbon source at 4-25 deg.C, and (b) recovering the novel endochitinase from the cultured medium.
