Journal of Phycology, EarlyView.Abstract Phosphoenolpyruvate carboxykinase (PEPCK) is involved in the conversion of phosphoenolpyruvate (PEP) to oxaloacetate (OAA). In addition to playing a role in gluconeogenesis in various organisms, PEPCK also functions in the C4 cycle to concentrate CO2 for photosynthesis in some C4 plants.

The Role of the [2Fe‐2S] Cluster of Escherichia coli IscR in Responding to Redox‐Cycling Agents
Molecular Microbiology, EarlyView.Redox cycling agents like phenazine methosulfate (PMS) are known for upsetting cellular redox balance. Here we describe how PMS leads to upregulation of the ISC and SUF Fe‐S cluster biogenesis pathways in Escherichia coli when PMS oxidizes the [2Fe‐2S]1+ cluster of the transcription factor IscR, thereby derepressing the operon encoding ISC and, when a ...

Zeitschrift für Naturforschung B, 1972 Diaphorase and transhydrogenase activities (system NADPH; dichlorophenolindophenol and NADPH;NAD, respectively) of ferredoxin-NADP reductase are increased by ferredoxin. Reduced thionicotinamide-NADP (TN-NADPH) only slightly inhibits these activities with no ferredoxin present in the assay, but the activity increments in the presence of ferredoxin are ...

New Phytologist, EarlyView.Summary With over 60 parallel origins representing evolutionary replicates, C4 photosynthesis is well‐suited for studying complex trait evolution. However, lineages with diverse C3–C4 intermediate species are scarce, leaving uncertainty in models of C4 evolution.

NADP-Malate Dehydrogenase Gene Evolution in Andropogoneae (Poaceae): Gene Duplication Followed by Sub-functionalization [PDF]
, 2017 • Background and Aims Plastid NADP-dependent malate dehydrogenase (MDH) catalyses the conversion of oxaloacetate to malate. In C4 plants, it is involved in photosynthetic carbon assimilation. In Poaceae, one NADP-MDH gene has been identified in rice (C3;

MAT2B regulates the protein level of MAT2A to preserve RNA N6-methyladenosine
Cell Death and DiseaseMAT2B works together with MAT2A to synthesize S-Adenosyl methionine (SAM) as the primary methyl donor. MAT2B, despite lacking catalytic activity, exerts regulatory control over the enzymatic activity of MAT2A.

Conserved spatial patterning of gene expression in independent lineages of C4 plants
New Phytologist, EarlyView.Summary C4 photosynthesis enhances carbon fixation efficiency by reducing photorespiration through the use of an oxygen‐insensitive carboxylase and spatial separation of photosynthesis between mesophyll and bundle sheath cells. The C4 pathway has evolved independently in > 60 plant lineages, but molecular mechanisms underpinning this convergence remain
