Jaws

This part is the E. coli codon optimized version of Jaws halorhodopsin.

Usage and Biology

Jaws is a halorhodopsin derived from Haloarcula (Halobacterium) salinarum (strain Shark) and is naturally red-shifted [1]. Compared to the wild-type HR (Halo57) it contains two mutations K200R and W214F that do not modify the absorption properties, but increase the photocurrent generated upon light irradiation.

Halorhodopsins are chloride inward pumps activated by light [1].

For the characterisation of this part an expression cassette was assembled and the results are presented on its page in Parts Registry: BBa_K4601202.
