Chitinase - High Purity and Specificity
Chitinase degrades chitin in the old epidermis or peritrophic matrix of insects, which ensures normal development and metamorphosis. In our previous work, we comprehensively studied the function of sfcht7 in sogatella furcifera however, the number and function of chitinase genes in s furcifera remain unknown.
We have cloned, sequenced, and examined the expression of genes from pine trees that appear to encode extracellular class ii chitinase. Nucleotide sequence analysis indicates a coding sequence composed of three exons interrupted by two introns at locations identical to those found in other chitinase genes that possess introns. One of the genes, pschi4, potentially encodes a protein that shares.
