Mycobacterium Phage Bxb1 gp47, DNA excisionase

KAIST DNA recombination via Bxb1 Int, Xis.png

This part is a protein coding part which encodes Bxb1 gp47, which is a DNA excisionase of Mycobacterium phage Bxb1.
The Bxb1 gp47 is a protein that directly binds to integrase-DNA complex. Without gp47, integrase-DNA complex recognize the "attL" and "attR" very weakly. The complex with gp47 strengthen the recognition and catalyzes DNA recombination reaction which is exactly reverse one done by integrase alone.

-The Bxb1 excisionase is a DNA recombinase, more precisely a member of serine integrase family. It forms complex with Bxb1 integrase. The complex recognizes specific sequences, called ''attL'' and ''attR'', and then catalyzes DNA recombination that is exact reverse reaction done by integrase alone.
+The Bxb1 gp47 is a protein that directly binds to integrase-DNA complex. Without gp47, integrase-DNA complex recognize the "attL" and "attR" very weakly. The complex with gp47 strengthen the recognition and catalyzes DNA recombination reaction which is exactly reverse one done by integrase alone.
