Determinants of nucleotide-binding selectivity of malic enzyme. [PDF]

open access: yesPLoS ONE, 2011
Malic enzymes have high cofactor selectivity. An isoform-specific distribution of residues 314, 346, 347 and 362 implies that they may play key roles in determining the cofactor specificity. Currently, Glu314, Ser346, Lys347 and Lys362 in human c-NADP-ME

Cofactor regeneration by a soluble pyridine nucleotide transhydrogenase for biological production of hydromorphone [PDF]

open access: yes, 2000
We have applied the soluble pyridine nucleotide transhydrogenase of Pseudomonas fluorescens to a cell-free system for the regeneration of the nicotinamide cofactors NAD and NADP in the biological production of the important semisynthetic opiate drug ...

In Vivo Selection for Formate Dehydrogenases with High Efficiency and Specificity toward NADP+

open access: yesACS Catalysis, 2020
The efficient regeneration of cofactors is vital for the establishment of biocatalytic processes. Formate is an ideal electron donor for cofactor regeneration due to its general availability, low reduction potential, and benign byproduct (CO2).

Preferential utilization of NADPH as the endogenous electron donor for NAD(P)H:quinone oxidoreductase 1 (NQO1) in intact pulmonary arterial endothelial cells [PDF]

open access: yes, 2009
The goal was to determine whether endogenous cytosolic NAD(P)H:quinone oxidoreductase 1 (NQO1) preferentially uses NADPH or NADH in intact pulmonary arterial endothelial cells in culture.

Characterization of theThreshold for NAD(P)H:quinone Oxidoreductase Activity in Intact Sulforaphane-treated Pulmonary Arterial Endothelial Cells [PDF]

open access: yes, 2011
Treatment of bovine pulmonary arterial endothelial cells in culture with the phase II enzyme inducer sulforaphane (5 μM, 24 h; sulf-treated) increased cell-lysate NAD(P)H:quinone oxidoreductase (NQO1) activity by 5.7 ± 0.6 (mean ± SEM)-fold, but intact ...

Identification and evolution of C4 photosynthetic pathway genes in plants

open access: yesBMC Plant Biology, 2020
Background NADP-malic enzyme (NAPD-ME), and pyruvate orthophosphate dikinase (PPDK) are important enzymes that participate in C4 photosynthesis. However, the evolutionary history and forces driving evolution of these genes in C4 plants are not completely

Adaptation responses in C4 photosynthesis of sweet maize (Zea mays L.) exposed to nicosulfuron

open access: yesEcotoxicology and Environmental Safety, 2021
Nicosulfuron is an ingredient in photosynthesis-inhibiting herbicides and has been widely used in corn post-emergence weed control. In the current study, a pair of sister lines, HK301 (nicosulfuron-tolerence, NT) and HK320 (nicosulfuron-sensitive, NS ...

A spatial analysis of physiological changes associated with infection of cotyledons of marrow plants with cucumber mosaic virus [PDF]

open access: yes, 1996
Changes in host primary metabolism associated with the compatible interaction between cucumber mosaic virus and cotyledons of the marrow plant (Cucurbita pepo L.) have been localized, first by measuring activities of key enzymes in infected and ...
