Part:BBa_K907000
Mycobacterium Phage Bxb1 gp35, DNA integrase
This part is a protein coding part which encodes Bxb1 gp35, which is a DNA integrase of Mycobacterium phage Bxb1. The Bxb1 integrase is a DNA recombinase, more precisely a member of serine integrase family. It recognizes specific sequences, called attB and attP, and then integrates, inverts, or excises dsDNA depending on the orientation of recognition sequences. We used this integrase to invert specific sequence in plasmid. The protein is well expressed in E.coli(strain MG1655) When it inverts DNA sequence, the attB and attP sequences are changed into attL and attR, as other DNA recombinases do. Another protein called Bxb1 gp47(BBa_K0907002) binds to integrase-DNA complexes and this complexes flips inverted DNA back into original sequence by regenerating attB and attP sequences.
