NAD 130-134 glutamate dehydrogenase 1 Homo sapiens 158-161 33020580-5 2020 Our structural analysis indicates that, binding to the regulatory sites in proximity of the antenna region, NADH acts as a positive allosteric modulator by enhancing both the affinity of the inhibitor GTP binding and inhibition of GDH catalytic activity. NAD 108-112 glutamate dehydrogenase 1 Homo sapiens 231-234 33020580-6 2020 We further show that the binding of GTP to the NADH-bound GDH activates a triangular allosteric network, interlinking the inhibitor with regulatory and catalytic sites. NAD 47-51 glutamate dehydrogenase 1 Homo sapiens 58-61
