EP3 — Oryza sativa Indica Group

Summary

BGIOSGA019833 (EP3, OiEP3) on chromosome 5 of Indica rice encodes a chitinase with beta-N-acetylglucosaminidase and chitinase activities (EC 3.2.1.14), belonging to the glycoside hydrolase family 19 and containing a chitin-binding domain. The gene is associated with chitin breakdown, cell wall macromolecule catabolic process, polysaccharide breakdown, amino sugar metabolism, membrane biogenesis, cell wall modification, transposition, killing of cells of other organisms, and defence response to fungi. Its product is localised extracellularly. EP3 is also associated with drought tolerance.
