Part:BBa_K2649004
ComE-NLS-VP16-NES NN2025
This part contains a human optimized coding sequence for ComE, the putative response regulator protein for the ComCDE two-component signaling pathway, native to Streptococcus mutans strain NN2025 (a bacteria common in the human oral cavity). Design elements were chosen to optimize expression and function of ComE in human cells. To be used as part of a functional sensing system, the ComE response regulator must be paired with the ComD histidine kinase receptor protein. When ComD binds to the S. mutans competence stimulating peptide, it autophosphorylates and transfers a phosphate group to an aspartic acid on ComE, enabling ComE to oligomerize and bind to specific DNA sequences to promote transcription. The ComE coding sequence is fused to a nuclear localization sequence (NLS), VP16 activating domain, and a nuclear export sequence (NES). It is in a pSB1C3 backbone and is BioBrick and MoClo compatible.
