New Phytologist, EarlyView.Summary Highly efficient phosphorus (P)‐use strategies have evolved in plants, allowing them to thrive in severely P‐impoverished environments. However, it remains unclear how allocating leaf P to biochemical fractions, including specific P‐containing metabolites, contributes to instantaneous photosynthetic P‐use efficiency (iPPUE) and the position of ...

Analysis of Multiple Isoenzyme Expression Among Twenty-Two Species of Mycoplasma and Acholeplasma [PDF]
, 1981 Crude extracts of triple-cloned, purified cultures of 22 species of Mycoplasma and Acholeplasma were examined for expression of 21 isozyme systems routinely used to type mammalian cells. Nine previously described enzymes (purine nucleoside phosphorylase,

Characterization of nuclear polyadenylated RNA-binding proteins in Saccharomyces cerevisiae. [PDF]
, 1994 To study the functions of heterogeneous nuclear ribonucleoproteins (hnRNPs), we have characterized nuclear polyadenylated RNA-binding (Nab) proteins from Saccharomyces cerevisiae.

FEBS Open Bio, Volume 16, Issue 1, Page 199-221, January 2026.Epigallocatechin‐3‐gallate (EGCG) acutely inhibited gluconeogenesis and enhanced glycolysis, glycogenolysis, and fatty acid oxidation in perfused rat livers. Mechanistic assays revealed mitochondrial uncoupling, inhibition of pyruvate carboxylation and glucose‐6‐phosphatase, shift of NADH/NAD+ ratios toward oxidation, and loss of membrane integrity ...

Multifaceted roles of metabolic enzymes of the Paracoccidioides species complex
Frontiers in Microbiology, 2014 Paracoccidioides species are dimorphic fungi, and are the etiologic agents of paracoccidioidomycosis (PCM), a serious disease of multiple organs. The large number of tissues colonized by this fungus suggests the presence of a variety of surface molecules

Responses of the marine diatom Thalassiosira pseudonana to changes in CO2 concentration: a proteomic approach [PDF]
, 2017 The concentration of CO2 in many aquatic systems is variable, often lower than the KM of the primary carboxylating enzyme Rubisco, and in order to photosynthesize efficiently, many algae operate a facultative CO2 concentrating mechanism (CCM).

Protein Science, Volume 34, Issue 12, December 2025.Abstract The nickel‐pincer nucleotide (NPN) cofactor catalyzes the racemization/epimerization of α‐hydroxy acids in enzymes of the LarA family. The established proton‐coupled hydride transfer mechanism requires two catalytic histidine residues that alternately act as general acids and general bases. Notably, however, a fraction of LarA homologs (LarAHs)

Specificity and kinetics of triose phosphate isomerase from chicken muscle [PDF]
Biochemical Journal, 1972 The isolation of crystalline triose phosphate isomerase from chicken breast muscle is described. The values of kcat. and Km for the reaction in each direction were determined from experiments over wide substrate-concentration ranges, and the reactions were shown to obey simple Michaelis–Menten kinetics.

The critical role of methylglyoxal and glyoxalase 1 in diabetic nephropathy [PDF]
, 2013 The discovery of increased formation of methylglyoxal (MG) by cell metabolism in high glucose concentration in vitro suggested possible relevance to diabetes and diabetes complications (1,2).
