Coenzyme Q Biosynthesis: An Update on the Origins of the Benzenoid Ring and Discovery of New Ring Precursors

Metabolites, 2021
Coenzyme Q (ubiquinone or CoQ) is a conserved polyprenylated lipid essential for mitochondrial respiration. CoQ is composed of a redox-active benzoquinone ring and a long polyisoprenyl tail that serves as a membrane anchor.

Bacterial Synthesis of p-Aminobenzoic Acid.

Experimental Biology and Medicine, 1943
SummaryRepresentative cultures of many bacterial genera were grown in culture media of known composition free of p-aminobenzoic acid. Culture filtrates and hydrolized whole cultures were assayed for p-aminobenzoic acid content employing the Acetobacter suboxydans microbiological method.

Gut Metabolite Indole‐3‐Propionic Acid Regulates Macrophage Autophagy Through PPT1 Inhibiting Aging‐Related Myocardial Fibrosis

Advanced Science, EarlyView.
IPA is an intestinal tryptophan metabolite whose effects decline with decreased heart function. Supplementing IPA can alleviate the aging‐related myocardial fibrosis through PPT1. PPT1 is a key protein localized to lysosomes, and IPA can restore macrophage autophagy function by regulating PPT1 expresssions, thereby reducing aging‐related myocardial ...
