Regulation of Leaf Senescence by Cytokinin, Sugars, and Light. Effects on NADH-Dependent Hydroxypyruvate Reductase [PDF]

, 1998
The aim of this study was to investigate the interactions between cytokinin, sugar repression, and light in the senescence-related decline in photosynthetic enzymes of leaves. In transgenic tobacco (Nicotiana tabacum) plants that induce the production of

A novel single‐cell NAD‐ME C4 subtype integrated with CAM and bicarbonate use in an aquatic plant

New Phytologist, EarlyView.
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of

Kinetics and functional diversity among the five members of the NADP-malic enzyme family from Zea mays, a C4 species

Photosynthesis Research, 2013
NADP-malic enzyme (NADP-ME) is involved in different metabolic pathways in several organisms due to the relevant physiological functions of the substrates and products of its reaction.

Discrete and cell‐specific hypoxic responses in Arabidopsis roots resolved by single‐nuclei transcriptomics

New Phytologist, EarlyView.
Summary With the intensification of unpredictable flooding events because of global warming, there is a need to understand how root cells perceive and respond to oxygen deprivation. The use of high‐throughput single‐nuclei RNA‐sequencing (snRNA‐Seq) allows the examination of gene expression profiles in discrete cell types.

Identification of the NADP⁺ Structural Binding Site and Coenzyme Effect on the Fused G6PD::6PGL Protein from Giardia lamblia

Biomolecules, 2019
Giardia lambia is a flagellated protozoan parasite that lives in the small intestine and is the causal agent of giardiasis. It has been reported that G. lamblia exhibits glucose-6-phosphate dehydrogenase (G6PD), the first enzyme in the pentose phosphate ...

Optimization of carbon and nitrogen utilization for enhanced photosynthesis, biomass and yield by coexpression of phosphoenolpyruvate carboxylase, aspartate aminotransferase and glutamine synthetase in Brassica juncea

Plant Biotechnology Journal, EarlyView.
Summary Coexpression of genes involved in carbon (C) and nitrogen (N) metabolism offers a promising avenue for improving crop yield. This study investigated the impact of coexpressing phosphoenolpyruvate carboxylase [ZmPEPC (P)], aspartate aminotransferase [GmAspAT (A)] and glutamine synthetase [NtGS (G)] in Brassica juncea to enhance plant yield ...

Structural Basis for a Bispecific NADP+ and CoA Binding Site in an Archaeal Malonyl-Coenzyme A Reductase*

Journal of Biological Chemistry, 2013
Background: Malonyl-CoA reductase of the CO2 assimilating 3-hydroxypropionate/4-hydroxybutyrate cycle reduces malonyl-CoA to malonic semialdehyde. Results: Malonyl-CoA reductase complexed with CoA and NADP+ was structurally characterized. Conclusion: The

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

, 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.
