Abstract

Abstract Various variants of photoprotein aequorin (pAQ440), useful for elucidating the mechanism of its luminescence and thereby extending the possibility of concrete applications of aequorin protein, and a process for producing variant aequorin proteins and provided, which variants are obtained by converting base(s) in a specified order of the base arrangement of aequorin gene into other base(s), or by deleting a certain bases in specified continued orders thereof, according to site-specific mutagenesis method.
