TurboID-N_AgrD-AIP

What is it?

This part includes four substance: TurboID, AIP, biotin,and N-AgrD. TurboID, a pair of biotin ligases, was designed to overcome the problem of slow existing biotin ligases. Using yeast display directed evolution techniques, the labeling time will be shorted to less than 10 minutes. This enables probing of dynamic biological processes with higher temporal resolution. AIP, autoinducing peptide, is a chemical released by S.aureus as it activates quorum sensing. N-AgrD is also a chemical involved in the cycle of virulence production, and it will direct TurboID toward the target site, AgrB.

what it does?

As AIP and N-AgrD directs TurboID toward AgrC and AgrD, TurboID will catalyze biotin and ATP it carried to produce Biotinyl-5'-AMP, which is used for protein labeling. When this substance reaches its active site, AgrA and AgrC, it will expand from the site with a maximum rage of 10 nano meter labeling the nearby proteins, especially the lysines. When a certain amount of biotinyl-5’-AMP is marked on AgrC and AgrA, the connection between the cell and the outside world will be completely cut off, the metabolic waste cannot be transported out of the cell, and the nutrients cannot enter the cell, which interferes with the biochemical reaction. Thus, achieving the goal of killing the bacteria.
