Coenzyme Engineering of a Hyperthermophilic 6-Phosphogluconate Dehydrogenase from NADP+ to NAD+ with Its Application to Biobatteries

open access: yesScientific Reports, 2016
Engineering the coenzyme specificity of redox enzymes plays an important role in metabolic engineering, synthetic biology, and biocatalysis, but it has rarely been applied to bioelectrochemistry.

The Potential of Phytochemicals to Overcome Multidrug Resistance in Metastatic Melanoma

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Metastatic melanoma is the most lethal form of skin cancer, accounting for most skin cancer‐related deaths. Immunotherapies and targeted therapies have improved overall and progression‐free survival rates in metastatic melanoma patients. The effectiveness of these therapies decreases due to multidrug resistance (MDR).

Cofactor Fingerprinting with STD NMR to Characterize Proteins of Unknown Function: Identification of a Rare cCMP Cofactor Preference [PDF]

open access: yes, 2004
Proteomics efforts have created a need for better strategies to functionally categorize newly discovered proteins. To this end, we have employed saturation transfer difference NMR with pools of closely related cofactors, to determine cofactor preferences.

Optimization of 4‐Amino‐2‐Pyridone Inhibitors of Proprotein Convertase Subtilisin/Kexin Type 9: Integrating Structure–Activity and Structure–Metabolism Relationships

open access: yesChemMedChem, EarlyView.
Green chemistry‐based late‐stage functionalization (LSF) of the anti‐proprotein convertase subtilisin/kexin type 9 (PCSK9) early lead compound 5c led to optimized analogs with improved metabolic stability/PCSK9 IC50 ratio. Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a key drug target for the treatment of different hypercholesterolemia ...

NADP-malic Enzyme OsNADP-ME2 Modulates Plant Height Involving in Gibberellin Signaling in Rice

open access: yesRice
Plants NADP-malic enzymes (NADP-MEs) act as a class of oxidative decarboxylase to mediate malic acid metabolism in organisms. Despite NADP-MEs have been demonstrated to play pivotal roles in regulating diverse biological processes, the role of NADP-MEs ...

Induction Kinetics of Photosystem I-Activated P700 Oxidation in Plant Leaves and Their Dependence on Pre-Energization [PDF]

open access: yes, 2010
Absorbance changes ¿A 810 were measured in pea (Pisum sativum L., cv. Premium) leaves to track redox transients of chlorophyll P700 during and after irradiation with far red (FR) light under various preillumination conditions in the absence and presence ...

NADP-dependent enzymes are involved in response to salt and hypoosmotic stress in cucumber plants.

open access: yesGeneral Physiology and Biophysics, 2017
Salt stress is one of the most damaging plant stressors, whereas hypoosmotic stress is not considered to be a dangerous type of stress in plants and has been less extensively studied.

Metabolic changes during cardiac regeneration in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,
