Contrasting catalytic and allosteric mechanisms for phosphoglycerate dehydrogenases [PDF]
Archives of Biochemistry and Biophysics, 2012 D-3-Phosphoglycerate dehydrogenases (PGDH) exist with at least three different structural motifs and the enzymes from different species display distinctly different mechanisms. In many species, particularly bacteria, the catalytic activity is regulated allosterically through binding of l-serine to a distinct structural domain, termed the ACT domain ...

Advanced Science, EarlyView.This study identifies a novel thermoregulatory mechanism in rice: TOGR3 partners with 26S proteasome subunits, including TT1, to drive thermoresponsive ubiquitin–proteasome activity, maintaining sugar homeostasis in stomatal regulation to balance growth and stress resistance.

A novel small-molecule inhibitor of 3-phosphoglycerate dehydrogenase. [PDF]
Mol Cell Oncol, 2016 Serine metabolism is likely to play a critical role in cancer cell growth. A recent study reports the identification of a novel small-molecule inhibitor of serine synthesis that targets 3-phosphoglycerate dehydrogenase (PHGDH), the first enzyme of the serine synthesis pathway, and selectively abrogates the proliferation of PHGDH overexpressing breast ...

Phosphoglycerate dehydrogenase genes differentially affect Arabidopsis metabolism and development
Plant Science, 2021 Unlike animals, plants possess diverse L-serine (Ser) biosynthetic pathways. One of them, the Phosphorylated Pathway of Serine Biosynthesis (PPSB) has been recently described as essential for embryo, pollen and root development, and required for ammonium and sulfur assimilation.

NIBAN2/FLII/RREB1 Axis Drives Glioma Stem Cell Malignancy via TLR3 Pathway Activation
Advanced Science, EarlyView.NIBAN2, highly expressed in glioma stem‐like cells (GSCs), assembles with FLII and transcription factor RREB1 to form a nuclear complex. This complex transcriptionally activates stemness‐associated genes (e.g., CD44, NANOG) and metabolic enzymes (e.g., LDHA), thereby sustaining both transcriptional and metabolic stemness programs.

Advanced Science, EarlyView.AAA ABSTRACT Protein glycosylation and phosphorylation are critical post‐translational modifications (PTMs) governing nearly all cellular functions, yet their analysis remains challenging due to reliance on costly and unsustainable enrichment materials.

The activation of 3‐phosphoglycerate dehydrogenase by L‐methionine [PDF]
FEBS Letters, 1970 Feedback inhibition within the metabolic pathways leading to amino acid biosynthesis is well known in a variety of organisms including higher plants [ 1,2] . Most of the information refers to the effects of amino acids on their own biosynthesis but Jensen [3] has recently pointed out that a regulatory superstructure connecting various metabolic ...

Inhibition of 3-phosphoglycerate dehydrogenase by
Biochemical Journal, 1968 1. l-Serine was shown to be a highly specific inhibitor of 3-phosphoglycerate dehydrogenase. 2. 3-Phosphoglycerate dehydrogenase is cold-labile with respect to its catalytic activity and to sensitivity to serine. 3. l-Serine protects the catalytic site as well as the inhibitor site. 4. Glycerol protects the catalytic site as well as the inhibitor site.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Pharmacogenetic CYP2B6 variants affect steroid hormone metabolism in human breast cancer cells
British Journal of Clinical Pharmacology, EarlyView.Common genetic CYP2B6 variants correlate with adverse breast cancer outcome. The oestrogen metabolites estriol and 16‐epiestriol, which are formed downstream of CYP2B6‐catalysed 16α/β‐hydroxytestosterone, may be linked to elevated breast cancer risk and might increase due to the demonstrated CYP2B6 variants‐related metabolic shifts.
