To determine the properties and structure of OsChia1b, a family 19 chitinase from Oryza sativa L. cv. Nipponbare (japonica ssp.), recombinant OsChia1b was produced in Esherichia coli cells and purified to homogeneity by chitin affinity column chromatography. OsChia1b was highly active against soluble chitinous substrate, but not against crystalline chitin, and clearly inhibited hyphal extension of Trichoderma reesei.
