The SLC25A4 gene provides the instructions for making a protein called adenine nucleotide translocase type 1 (ANT1).ANT1 functions in mitochondria, which are structures within cells that convert the energy from food into a form that cells can use.he SLC25A4 gene provides the instructions for making a protein called adenine nucleotide translocase type 1 (ANT1).
Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid. The linear sequence of amino acids within a protein is considered the primary structure of the protein.Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries.The largest group of amino acids have nonpolar side chains.he linear sequence of amino acids within a protein is considered the primary structure of the protein.
