Abstract
A protein for visual color recognition and the like, the protein having a channel activity and including an amino acid residue different from the amino acid residue present in a first amino acid sequence represented by SEQ ID NO: 1, at a position or positions corresponding to one or two or more selections from the group consisting of the following positions in the first amino acid sequence: positions 53, 83, 87, 117, 120, 124, 137, 139, 142, 143, 146, 150, 169, 173, 177, 198, 204, 216, 217, 218, 231, 238, 245, and 247.
Claims7
A protein comprising an amino acid sequence having at least 98% identity to SEQ ID NO. 1,
- wherein the amino acid sequence comprises one or more amino acid substitutions selected from (i) Y117F;
- (ii) L146A and Y217F;
- and (iii) T147C, G151A, and Y217F, at the position or positions corresponding to the one or more positions in the amino acid sequence represented by SEQ ID NO:
- 1, and
- wherein the protein has a channel activity and wherein the λmax wavelength of the protein is shorter than the λmax wavelength of the protein consisting of the amino acid sequence of SEQ ID NO:
- 1.
