Cloning of a Newly discovered Na pumping Halorhodopsin from marine flavobacterium Krokinobacter eikastus
We used a Gibson reation with IDT G Blocks and IGEM pSB1C3 to clone KR2 halorhodopsin into pSB1C3 BioBrick backbone.
Key Reference- A light-driven sodium ion pump in marine bacteria. Inoue et al. Nature Communications DOI: 10.1038/ncomms2689 April 9, 2013.
