Literature summary for 2.4.1.207 extracted from
- Xyloglucan endotransglucosylase/hydrolases (XTHs) are inactivated by binding to glass and cellulosic surfaces, and released in active form by a heat-stable polymer from cauliflower florets (2017), J. Plant Physiol., 218, 135-143 .

| additional information | XTHs in dilute solution bind to diverse surfaces (e.g. glass and cellulose), and certain cold-water-extractable, heat-stable polymers (CHPs), e.g. from cauliflower florets, can re-solubilise the bound enzyme, re-activating it. Cell walls prepared from cauliflower florets, mung bean shoots and Arabidopsis cell-suspension cultures each contain endogenous, tightly bound, inactive XTHs, which are likewise rapidly solubilised and thus activated by cauliflower XTH-activating factor (XAF). Analysis of XTH-activating factor (XAF) activity of CHP preparations from diverse plant sources, CHPs from all plants tested possess XAF activity, overview | Brassica oleracea var. botrytis |

| physiological function | xyloglucan endotransglucosylase (XET) activity, which cuts and re-joins hemicellulose chains in the plant cell wall, contributing to wall assembly and growth regulation, is the major activity of XTH proteins. During purification, XTHs often lose XET activity which, however, is restored by treatment with certain cold-water-extractable, heat-stable polymers (CHPs), e.g. from cauliflower florets | Vigna radiata |
