The fact that all amino acids contain R groups with different properties is the main reason proteins fold. And, specifically, I wanna focus on the catabolism of amino acids and how that catabolism allows us to produce ATP inside of ourselves. This study has identified REPTOR and REPTOR-BP , both leucine zipper DNA-binding proteins, as transcription factors downstream of TORC1 that are required for approximately 90% of the transcriptional induction that occurs upon TORC1 inhibition in Drosophila.
