[AAV2]-Rep-VP123_P5-TATAless (ViralBrick-587KO-BAP)
The Biotinylation Acceptor peptide motif, including a knockout of the natural HSPG tropism, inserted into the 587 loop of [AAV2]-Rep-VP123_p5-TATAless
Usage and Biology
The Biotinylation Acceptor Peptide (BAP) is a 15 amino acid long peptide identified by Schatz J., 1993 in an library screening approach. This peptide with the sequence 5' - GLNDIFEAQKIEWHE - 3' contains a central lysine that is specifically biotinylated by the prokaryotic enzyme biotin holenzyme synthetase, encoded in the BirA gene of E. coli. Specific biotinylation of this peptide sequence can be performed in vivo by contransfecting a plasmid with the BirA gene as described for the AAV in Arnold et al.; 2006 or by an in vitro coupling approach using the purified Escherichia coli enzyme biotin ligase (BirA).
