Protein enzymes are encoded by genes.
Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Many proteins are enzymes that catalyse biochemical reactions and are vital to metabolism. The number of proteins encoded in a genome roughly corresponds to the number of genes (although there may be a significant number of genes that encode RNA of protein, e.g. ribosomal RNAs). Proteins are assembled from amino acids using information encoded in genes. Proteins are the chief actors within the cell, said to be carrying out the duties specified by the information encoded in genes.
