Design Notes and Sources
BLAST search using translated sequence of BBa_K729004, from which only the nucleotide sequence that coded for the DNase was identified and isolated
The gene sequence for micrococcal DNase was obtained from BBa_K729004, a part comprising DsbA 2-19 fused to the N-terminal of micrococcal nuclease made by [http://2012.igem.org/Team:University_College_London Team UCL 2012]. The part sequence was not annotated, and as such we ran a [http://blast.ncbi.nlm.nih.gov/blast/Blast.cgi?PROGRAM=blastp&PAGE_TYPE=BlastSearch&LINK_LOC=blasthome Protein BLAST search] using the part's translated sequence to identify the bases that coded for our desired peptide [1]. The sequence for micrococcal DNase was adopted as-is from said part, without further codon optimization.
A Hisx6 tag is added at the C-terminus for ease of protein purification using metal-affinity chromatography.
