| Enzyme Function | FUNCTION: Endo-1,4-beta-xylanase involved in the hydrolysis of xylan, a major structural heterogeneous polysaccharide found in plant biomass representing the second most abundant polysaccharide in the biosphere, after cellulose. Required for planr infection and the appearance of secondary lesions. {ECO:0000269|PubMed:16404950}. |

| Interact With | |
| Induction | INDUCTION: Expression is maximal when xylan is the only carbon source, and repressed by glucose. Expression is detected from the beginning of tomato leaves infection in the just-inoculated leaves, and the level sof transcript increased between 24 and 48 hours postinfection simultaneously with the appearance of visible lesions on the leaves. {ECO:0000269|PubMed:16404950}. |
