Leader Peptide Gene At Biology Glossary

What is it? A small gene within the attenuator control region of repressible amino acid operons. Translation of a specific leader peptide tests for the concentration of a specific amino acid or set of amino acids in the cell. If the concentration is high transcription is terminated in the attenuator, if low continued leading to the production of enzymes for amino acid synthesis and hence more amino acid. See leader transcript.
