Abstract

An open reading frame encoding the chitinase gene and its signal sequence was cloned from the Vibrio parahaemolyticus KN1699 genome. An expression plasmid containing the gene was introduced into Escherichia coli cells, and recombinant chitinase (Pa-rChi) was produced and secreted into the culture medium with the aid of the signal peptide. Pa-rChi was purified and its substrate specificity was determined.
