metabolism | model-based design, construction, and characterization of controller cells to modulate the external AI-2 environment, the cells are designed via the compartmentalization of different aspects of AI-2 processing: uptake (lsrACDB), phosphorylation (lsrK), and degradation (lsrFG), mathematical model overview | Escherichia coli |
physiological function | the enzyme is responsible for the phosphorylation of autoinducer 2, and thereby attenuating cell-cell communication among bacterial populations. The bacterial signal molecule autoinducer-2 is secreted as a quorum sensing signal. The enzyme LsrK increases the net uptake rate by limiting secretion of AI-2 back into the extracellular environment. LsrK-mediated phosphorylation of AI-2 blocks export back to the extracellular milieu so that accumulated AI-2P binds the regulatory protein LsrR | Escherichia coli |
