Luciferase from the anthozoan coelenterate Renilla reniformis (Renilla luciferin:oxygen 2-oxidoreductase (decarboxylating), EC 1.13.12.5.) catalyzes the bioluminescent oxidation of Renilla luciferin producing light (lambdaB 480 nm, QB 5.5%), oxyluciferin, and CO2 (Hori, K., Wampler, J.E., Matthews, J.C., and Cormier, M.J. (1973), Biochemistry 12, 4463). Using a combination of ion-exchange, molecular-sieve, sulfhydryl-exchange, and affinity chromatography, luciferase has been purified, approximately 12 000-fold with 24% recovery, to homogeneity as judged by analysis with disc and sodium dodecyl sulfate-polyacrylamide gel electrophoresis, gel filtration, and ultracentrifugation. Renilla luciferase is active as a nearly spherical single polypeptide chain monomer of 3.5 X 10(4) daltons having a specific activity of 1.8 X 10(15) hp s-1 mg-1 and a turnover number of 111 mumol min-1 mumol-1 of enzyme. This enzyme has a high content of aromatic and hydrophobic amino acids such that it has an epsilon280nm 0.1% of 2.1 and an average hydrophobicity of 1200 cal residue-1. The high average hydrophobicity of luciferase, which places it among the more hydrophobic proteins reported, is believed to account, at least in part, for its tendency to self-associate forming inactive dimers and higher molecular weight species.
