Niacinamide 114-126 ferredoxin reductase Homo sapiens 29-55 22542899-9 2012 The overall findings indicate that in FNR the volume of the residue at position 266 is essential to attain the catalytic architecture between the nicotinamide and isoalloxazine rings at the active site and, therefore, for an efficient HT process. Niacinamide 146-158 ferredoxin reductase Homo sapiens 38-41 16216071-2 2005 During hydride transfer it is proposed that the FNR C-terminal Tyr is displaced by the nicotinamide. Niacinamide 87-99 ferredoxin reductase Homo sapiens 48-51 7677850-1 1995 The crystal structure of ferredoxin-NADP+ reductase (FNR) suggests that Ser96 is directly involved in hydride transfer between the isoalloxazine moiety of FAD and the nicotinamide ring of NADP(H). Niacinamide 167-179 ferredoxin reductase Homo sapiens 25-51 21538059-5 2012 In particular, the side chain of the C-terminal Y303 in Anabaena FNR appears key to providing the optimum geometry by reducing the stacking probability between the isoalloxazine and nicotinamide rings, thus providing the required co-linearity and distance among the N5 of the flavin cofactor, the C4 of the coenzyme nicotinamide and the hydride that has to be transferred between them. Niacinamide 182-194 ferredoxin reductase Homo sapiens 65-68 21538059-5 2012 In particular, the side chain of the C-terminal Y303 in Anabaena FNR appears key to providing the optimum geometry by reducing the stacking probability between the isoalloxazine and nicotinamide rings, thus providing the required co-linearity and distance among the N5 of the flavin cofactor, the C4 of the coenzyme nicotinamide and the hydride that has to be transferred between them. Niacinamide 316-328 ferredoxin reductase Homo sapiens 65-68 20471952-7 2010 The architecture of the WT FNR active site precisely contributes to reduce the stacking probability between the isoalloxazine and nicotinamide rings in the catalytically competent complex, modulating the angle and distance between the N5 of the FAD isoalloxazine and the C4 of the coenzyme nicotinamide to values that ensure efficient HT processes. Niacinamide 130-142 ferredoxin reductase Homo sapiens 27-30 20471952-7 2010 The architecture of the WT FNR active site precisely contributes to reduce the stacking probability between the isoalloxazine and nicotinamide rings in the catalytically competent complex, modulating the angle and distance between the N5 of the FAD isoalloxazine and the C4 of the coenzyme nicotinamide to values that ensure efficient HT processes. Niacinamide 290-302 ferredoxin reductase Homo sapiens 27-30 10744737-0 2000 Competition between C-terminal tyrosine and nicotinamide modulates pyridine nucleotide affinity and specificity in plant ferredoxin-NADP(+) reductase. Niacinamide 44-56 ferredoxin reductase Homo sapiens 121-149 7677850-1 1995 The crystal structure of ferredoxin-NADP+ reductase (FNR) suggests that Ser96 is directly involved in hydride transfer between the isoalloxazine moiety of FAD and the nicotinamide ring of NADP(H). Niacinamide 167-179 ferredoxin reductase Homo sapiens 53-56 7677850-6 1995 However, spectral perturbations induced by NADP+ binding to FNR-S96V strongly resemble those elicited by the binding of 2"-monophosphoadenosine-5"-diphosphoribose, a substrate analog lacking the nicotinamide ring, both to the mutant and wild-type enzymes. Niacinamide 195-207 ferredoxin reductase Homo sapiens 60-63 3394171-6 1988 These data support the conclusion about the existence of second nicotinamide coenzyme binding centre in adrenodoxin reductase.
