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.
Like other natural proteinogenic amino acids, cysteine and selenocysteine have L chirality in the older D / L notation based on homology to D - and L-glyceraldehyde. In the newer R / S system of designating chirality, based on the atomic numbers of atoms near the asymmetric carbon, they have R chirality, because of the presence of sulfur or ...
2,4 Dienoyl-CoA reductase also known as DECR1 is an enzyme which in humans is encoded by the DECR1 gene which resides on chromosome 8. This enzyme catalyzes the following reactions [ 1 ] [ 2 ] [ 3 ] DECR1 participates in the beta oxidation and metabolism of polyunsaturated fatty enoyl-CoA esters.
[2] Researchers have used strains of E. coli auxotrophic for specific amino acids to introduce non-natural amino acid analogues into proteins. For instance cells auxotrophic for the amino acid phenylalanine can be grown in media supplemented with an analogue such as para-azido phenylalanine.

NEW YORK (Reuters) -The man accused of killing a woman sleeping on a New York City subway car by setting her on fire after what prosecutors say was a night of heavy drinking pleaded not guilty to ...
The Van Slyke determination is a chemical test for the determination of amino acids containing a primary amine group. It is named after the biochemist Donald Dexter Van Slyke (1883-1971). [1] One of Van Slyke's first professional achievements was the quantification of amino acids by the Van Slyke determination reaction. [2]
