XTH-activating factor
-
an endogenous cold-water-extractable, heat-stable polymer(s) (CHP) from cauliflower florets acts as an XTH-activating factor (XAF), promoting the XET activity of XTHs. The XTH-activating factors from plants desorb and thereby activate wall-bound XTHs. CHP specifically desorbed wall-bound XTHs, but not beta-glucosidases, phosphatases or peroxidases. CHP preparations from 25 angiosperms all possess XAF activity but have no consistent monosaccharide composition. Of 11 individual plant polymers tested, only gum arabic and tamarind xyloglucan are XAF-active, albeit less so than CHP. On gel-permeation chromatography, XAF-active cauliflower CHP elutes with a molecular weight of 7000-140000, although no specific sugar residue(s) co-elute exactly with XAF activity. Cauliflower XAF activity survives cold alkali and warm dilute TFA (which break ester and glycofuranosyl linkages, respectively), but is inactivated by hot 2 M TFA (which breaks glycopyranosyl linkages). Cauliflower XAF activity is remarkably stable to diverse glycanases and glycosidases, sugar composition of XAF-active CHPs from diverse plants and evaluation of XAF activity, detailed overview. The ability of CHP to solubilize XTHs from Arabidopsis cell walls is mimicked by NaCl and CaCl2. The effect plateaues above about 30 mM CaCl2, while the CHP effect does not plateau even at the highest concentration tested (1.8 mg/ml). The relative effect of CHP is greatest (34fold promotion) in the absence of CaCl2, but strong CHP effects (4.6 to 9.1fold promotion) and much higher absolute XET activities are still detected in the presence of 15 mM CaCl2, indicating synergy between CHP and the inorganic salt. Xyloglucan endoglucanase (XEG) shows some (moderate) ability to inactivate XAF. CHP has a stronger XAF effect on more dilute cell-wall suspensions
