Part:BBa_K2549011

ZF21.16 split N

This part is the N-terminal fragment of the zinc finger. Amino acid residues of the recognition helices for three-finger arrays are substituted by the reported synthetic zinc finger 21.16 residues[1] on the basis of the BCR_ABL-1 artificial zinc finger[2]. Splicing site between the 48 and 49 residues is chosen as is reported to function the second highest among the tested 12 splicing sites[2]. This site is chosen as the +1 position residue for the Cfa’C has to be a cysteine[3]. It can be fused to the Cfa’N(Click here to see!) intein.
