Abstract

An object of the present invention is to provide a novel fluorescent protein derived from favia favus . The present invention provides a fluorescent protein derived from favia favus having the following properties: (1) an excitation maximum wavelength is 507 nm; (2) a fluorescence maximum wavelength is 517 nm; (3) a molar absorption coefficient at 482 nm is 80,000; (4) a quantum yield is 0.68; and (5) pH sensitivity of the fluorescence maximum is stable at pH 5 to pH 11.

Claims (5)

1. An isolated DNA comprising any of the following nucleotide sequences:

(a) the nucleotide sequence shown in SEQ ID NO: 2, 13, 15, 17, 19, or 21; or

(b) the nucleotide sequence of SEQ ID NO: 2 with 1 to 60 nucleotide substitutions, and encoding a fluorescent protein.

2. A recombinant vector having the DNA of claim 1 .

3. A transformant having the DNA of claim 1 .
