Insight into the Carboxyl Transferase Domain Mechanism of Pyruvate Carboxylase from \u3cem\u3eRhizobium etli\u3c/em\u3e [PDF]

open access: yes, 2009
The effects of mutations in the active site of the carboxyl transferase domain of Rhizobium etli pyruvate carboxylase have been determined for the forward reaction to form oxaloacetate, the reverse reaction to form MgATP, the oxamate-induced ...

ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

open access: yes, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Icaritin Ameliorates Cisplatin‐Induced Mitochondrial Metabolic Dysfunction‐Associated Nephrotoxicity and Synergistically Potentiates Its Antitumor Efficacy

open access: yesAdvanced Science, EarlyView.
In this study, scRNA‐seq and chemoproteomics are integrated to characterize CDDP‐bound proteins at single‐cell resolution in tumor‐bearing mice. Additionally, the research demonstrates that ICA alleviates CDDP‐induced nephrotoxicity while enhancing its chemotherapeutic efficacy.

Kinetic modelling of β‐cell metabolism reveals control points in the insulin‐regulating pyruvate cycling pathways

open access: yesIET Systems Biology, 2023
Insulin, a key hormone in the regulation of glucose homoeostasis, is secreted by pancreatic β‐cells in response to elevated glucose levels. Insulin is released in a biphasic manner in response to glucose metabolism in β‐cells.

NAD⁺ Reduction in Glutamatergic Neurons Induces Lipid Catabolism and Neuroinflammation in the Brain via SARM1

open access: yesAdvanced Science, EarlyView.
NAD⁺ homeostasis maintains neuronal integrity through opposing actions of NMNAT2 and SARM1. Loss of NMNAT2 in glutamatergic neurons reprograms cortical metabolism from glucose to lipid catabolism, depletes lipid stores, and triggers inflammation and neurodegeneration.

Structural classification of biotin carboxyl carrier proteins [PDF]

open access: yes, 2012
We gathered primary and tertiary structures of acyl-CoA carboxylases from public databases, and established that members of their biotin carboxylase (BC) and biotin carboxyl carrier protein (BCCP) domains occur in one family each and that members of ...

Targeting Endothelial KDM5A to Attenuate Aging and Ameliorate Age‐Associated Metabolic Abnormalities

open access: yesAdvanced Science, EarlyView.
This study identifies endothelial KDM5A as a key regulator of aging. KDM5A deficiency accelerates aging by enhancing H3K4me3‐mediated FABP4 expression, disrupting fatty acid metabolism, and promoting multi‐organ senescence. KDM5A restoration or FABP4 inhibition reverses these adverse effects and extends lifespan, positioning the KDM5A/FABP4 axis as a ...

Hypoxia-mediated repression of pyruvate carboxylase drives immunosuppression

open access: yesBreast Cancer Research
Background Metabolic plasticity mediates breast cancer survival, growth, and immune evasion during metastasis. However, how tumor cell metabolism is influenced by and feeds back to regulate breast cancer progression are not fully understood.

Acute control of fatty acid synthesis by cyclic AMP in the chick liver cell: possible site of inhibition of citrate formation.

open access: yesJournal of Lipid Research, 1979
Glucagon and N,(6)O(2)-dibutyryl cyclic adenosine 3‘,5‘-cyclic monophosphate (Bt(2)cAMP) inhibit fatty acid synthesis from acetate by more than 90% and prevent citrate formation in chick hepatocytes metabolizing glucose.
