Xyl5 — Fusarium oxysporum f. sp. lycopersici 4287

Summary

FOXG_02768 (Xyl5) on chromosome 8 of Fusarium oxysporum f. sp. lycopersici 4287 encodes a glycoside hydrolase family 5 protein with endo-(1,6)-beta-D-glucanase, xylan 1,4-beta-xylosidase, glucan exo-1,3-beta-glucosidase, and beta-glucosidase activities, and metal binding. The gene is associated with fungal-type cell wall beta-glucan metabolism, glucan breakdown, cell wall organization, and mating projection tip cell wall disassembly. The product localizes to the mating projection actin fusion focus, division septum, cell-bound compartment, and extracellular space. Studies of related genes in other species link the family to similar enzymatic functions, including EC 3.2.1.75, 3.2.1.58, and 3.2.1.37 activities.
