Researchers at the University of Ulm have described the first autonomous walking small-molecule machine: a simple phosphate group. The walker travels along a hydroxy-paved molecular track using an alternating series of cyclization and ring-opening reactions. #chemsky 🧪

One gene can code for proteoforms with: ◼️ different functions ◼️ different sequences ◼️ different regulation ◼️ different cell type expression Such examples should inform the interpretation of gene deletion experiments seeking to infer "gene functions".
