SIRT4 is a mitochondrial ADP-ribosyltransferase that inhibits mitochondrial glutamate dehydrogenase 1 activity, thereby downregulating insulin secretion in response to amino acids. [7] A deacetylation of malonyl-CoA decarboxylase enzyme by SIRT4 represses the enzyme activity, inhibiting fatty acid oxidation in muscle and liver cells.
Antimicrobial peptides have been demonstrated to kill Gram negative and Gram positive bacteria, [1] enveloped viruses, fungi and even transformed or cancerous cells. [2] Unlike the majority of conventional antibiotics it appears that antimicrobial peptides frequently destabilize biological membranes , can form transmembrane channels , and may ...
The first sirtuin was identified in yeast (a lower eukaryote) and named sir2. In more complex mammals, there are seven known enzymes that act in cellular regulation, as sir2 does in yeast. These genes are designated as belonging to different classes (I-IV), depending on their amino acid sequence structure. [20]
Teixobactin (/ ˌ t eɪ k s oʊ ˈ b æ k t ɪ n /) is a peptide-like secondary metabolite of some species of bacteria, that kills some gram-positive bacteria.It appears to belong to a new class of antibiotics, and harms bacteria by binding to lipid II and lipid III, important precursor molecules for forming the cell wall.

A study in the UK found that people who ate a keto diet for up to 12 weeks experienced rises in cholesterol, drops in good gut bacteria, and less efficient processing of carbs. Alexander Spatari ...
Alternative methods of classification include: method of killing (pore-forming, nuclease activity, peptidoglycan production inhibition, etc.), genetics (large plasmids, small plasmids, chromosomal), molecular weight and chemistry (large protein, peptide, with/without sugar moiety, containing atypical amino acids such as lanthionine), and method of production (ribosomal, post-ribosomal ...
