title: Isolation and characterization of a chitinase cDNA from the entomopathogenic fungus, Metarhizium anisopliae.
abstract: A novel chitinase gene was isolated from Metarhizium anisopliae grown in a medium containing chitin as the sole carbon source. Comparisons of nucleotide sequence of the isolated gene with those of other fungal chitinase genes showed low sequence identity (24.4-36.4%) except for the active site of chitinase. In addition, molecular mass determination of the fused gene product separated on a gel showed that the fused chitinase seems to be about 70 kDa, while the molecular mass calculated from the deduced amino acid sequence can be about 58 kDa. These molecular masses were different from values of 33 kDa for an endochitinase and 110 kDa for an exochitinase (N-acetylglucosaminidase) from M. anisopliae published previously.
