| Enzyme Function | FUNCTION: Catalyzes endohydrolysis of 1,4-beta-D-glucosidic linkages in xyloglucan with retention of the beta-configuration of the glycosyl residues in xyloglucan degradation. Cleaves the backbone of the 3 major types of natural xyloglucans (seed galactoxyloglucan from tamarind kernel, dicot fucogalactoxyloglucan from lettuce leaves, and solanaceous arabinogalactoxyloglucan from tomato fruit), to produce xyloglucan oligosaccharides. {ECO:0000269|PubMed:24463512}. |
