RT thaliana xyloglucan endotransglucosylase/hydrolases, XTH15 and XTH31,
RT heterologously produced in Pichia.";
RL Phytochemistry 112:160-169(2015).
CC -!- FUNCTION: Catalyzes xyloglucan endohydrolysis (XEH) and/or
CC endotransglycosylation (XET). Cleaves and religates xyloglucan
CC polymers, an essential constituent of the primary cell wall, and
CC thereby participates in cell wall construction of growing tissues. Has
CC a high XET activity, but little or no XEH activity in vitro. Acceptor
CC preferences are XXXGol > XLLGol = XLFGol > XXLGol > XXFGol.
CC {ECO:0000269|PubMed:25446234}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=breaks a beta-(1->4) bond in the backbone of a xyloglucan and
CC transfers the xyloglucanyl segment on to O-4 of the non-reducing
CC terminal glucose residue of an acceptor, which can be a xyloglucan or
CC an oligosaccharide of xyloglucan.; EC=2.4.1.207;
CC Evidence={ECO:0000269|PubMed:25446234};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=xyloglucan + H2O = xyloglucan oligosaccharides.; EC=3.2.1.151;
CC Evidence={ECO:0000269|PubMed:25446234};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=31 uM for XXXGol {ECO:0000269|PubMed:25446234};
CC Note=KM for xyloglucan as donor substrate is 2.87 mg/ml. KM is quoted
CC in mg/ml, not uM, because XTHs are able to utilise any segment of the
CC polysaccharide chain equally well, not just one site per molecule as
CC with the acceptor. {ECO:0000269|PubMed:25446234};
CC pH dependence:
CC Optimum pH is 6 for the XET activity. {ECO:0000269|PubMed:25446234};
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall {ECO:0000305}. Secreted,
CC extracellular space, apoplast {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Strongly expressed in roots, hypocotyls and
CC cotyledons. Aslo detected in inflorescence stems and in the carpels and
CC styles in flowers. {ECO:0000269|PubMed:16830179}.
CC -!- INDUCTION: Down-regulated by auxin (PubMed:11673616). Down-regulated by
CC aluminum (PubMed:21285327). Repressed by far-red light (FRc)
CC (PubMed:14645728). {ECO:0000269|PubMed:11673616,
CC ECO:0000269|PubMed:14645728, ECO:0000269|PubMed:21285327}.
CC -!- PTM: Contains at least one intrachain disulfide bond essential for its
CC enzymatic activity. {ECO:0000250}.
CC -!- DISRUPTION PHENOTYPE: No visible growth defects, but increased aluminum
CC resistance. {ECO:0000269|PubMed:23776189}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 16 family. XTH group 2
CC subfamily. {ECO:0000305}.
