4.2.1.115 additional information the dehydratase does not require the addition of exogenous cofactor NAD(P)+ 692984 4.2.1.115 additional information the hexose ring occupies a non-catalytic conformation with respect to the coenzyme 729735 4.2.1.115 NAD(P)+ dependent on, tightly bound 691202 4.2.1.115 NAD+ - 692952, 694211 4.2.1.115 NADP+ binding and binding site structure, overview. Function of Tyr164 is related to its bulkiness in the relay mechanism 729735 4.2.1.115 NADP+ NADP+/NADPH is tightly bound to FlaA1 692980 4.2.1.115 NADPH binding and binding site structure, overview. Function of Tyr164 is related to its bulkiness in the relay mechanism 729735 4.2.1.115 NADPH superposition of the NADPH binding domain of Mg534 with CapE highlights a large conformational change of the substrate binding domain that reflects the dynamic of the structure during the catalysis. In absence of the substrate, the domain is rotated and closes the substrate binding pocket 748176
