EP3 — Oryza sativa Indica Group

Summary

BGIOSGA023633 (EP3, OiEP3) on chromosome 6 of Indica rice encodes a chitinase with beta-N-acetylglucosaminidase and chitinase activities (EC 3.2.1.14) and chitin binding, belonging to the glycoside hydrolase family 19 and chitin-binding domain families. The gene is associated with chitin breakdown, cell wall macromolecule catabolic process, polysaccharide breakdown, amino sugar metabolism, carbohydrate metabolism, defence response to fungi, defense response, membrane biogenesis, cell wall modification, transposition, and killing of cells of other organism. It is linked to drought tolerance and localises to the extracellular region. Related genes in other species, including 26 kDa endochitinase 1 and proteins such as RQ30, CBAP, CH16, and CH6, are associated with similar hydrolytic and defence functions.
