    en.wikipedia.org/wiki/Sirtuin

    [2] [3] They are ancient in animal evolution and appear to possess a highly conserved structure throughout all kingdoms of life. [2] Chemically, sirtuins are a class of proteins that possess either mono- ADP-ribosyltransferase or deacylase activity, including deacetylase, desuccinylase , demalonylase , demyristoylase and depalmitoylase activity.

  4. Kynurenine - Wikipedia

    en.wikipedia.org/wiki/Kynurenine

    l-Kynurenine is a metabolite of the amino acid l-tryptophan used in the production of niacin. Kynurenine is synthesized by the enzyme tryptophan dioxygenase , which is made primarily but not exclusively in the liver, and indoleamine 2,3-dioxygenase , which is made in many tissues in response to immune activation.

    en.wikipedia.org/wiki/4-Hydroxyphenylglycine

    4-Hydroxyphenylglycine (HPG) is a non-proteogenic amino acid found in vancomycin and related glycopeptides. HPG is synthesized from the shikimic acid pathway and requires four enzymes to synthesize: [1] Both L- and D-HPG are used in the vancomycin class of antibiotics.

    en.wikipedia.org/wiki/Pyrrolysine

    Pyrrolysine (symbol Pyl or O; [2] encoded by the 'amber' stop codon UAG) is an α-amino acid that is used in the biosynthesis of proteins in some methanogenic archaea and bacteria; [3] [4] it is not present in humans. It contains an α-amino group (which is in the protonated – NH +
