Abstract
A gene encoding chitinases from Aeromonas sp. No. 10S-24 was cloned into Escherichia coli DH5 alpha using pUC19, and its nucleotides were sequenced. The chitinase gene was clustered in ORFs (open reading frame) 1 to 4, in a 8-kb fragment of DNA. ORF-1 consisted of 1608 bp encoding 535 amino acid residues, and ORF-2 consisted of 1425 bp encoding 474 amino acid residues. ORF-3 was 1617 bp long and encodes a protein consisting of 538 amino acids. ORF-4 encodes 287 amino acids of the N-terminal region. The amino acid sequences of ORF-1 and ORF-3 share sequence homology with chitinase D from Bacillus circulans, and chitinase A and B from Streptomyces lividans. The amino acid sequence of ORF-2 shared sequence homology with chitinase II from Aeromonas sp. No. 10S-24, and chitinase from Saccharopolyspora erythraea. A region of the sequence starting from Ala-28 of the amino acid sequence of ORF-3 coincided with the N-terminal amino acid sequence of chitinase III from Aeromonas sp. No. 10S-24.Entities:
