Cloning and expression of the cDNA coding for aequorin, a bioluminescent calcium-binding protein

Cloning and expression of the cDNA coding for aequorin, a bioluminescent calcium-binding protein. Prasher, Douglas; McCann, Richard O.; Cormier, Milton J. (Dep. Biochem., Univ. Georgia, Athens, GA 30602, USA). Biochem. Biophys. Res. Commun., 126(3), 1259-68 (English) 1985. CODEN: BBRCA9. ISSN: 0006-291X. DOCUMENT TYPE: Journal CA Section: 3 (Biochemical Genetics) Aequorin is a bioluminescent protein from the hydromedusan Aequorea victoria which consists of a polypeptide chain (apoaequorin), coelenterate luciferin [55779-48-1], and bound O. Aequorin produces blue light upon binding Ca2+. Six recombinant pBR322 plasmids were isolated which contain apoaequorin cDNA sequences. A mixed, synthetic oligonucleotide probe was used to identify these cDNAs. An ext. of an E. coli strain possessing the largest cDNA contained apoaequorin. This apoaequorin can be converted to aequorin in the presence of coelenterate luciferin, 2-mercaptoethanol, and O2. This cDNA is therefore apparently full-length.

Oplophorus luciferin, bioluminescent substance of the decapod shrimps, Oplophorus spinosus and Heterocarpus laevigatus

Oplophorus luciferin, bioluminescent substance of the decapod shrimps, Oplophorus spinosus and Heterocarpus laevigatus. Inoue, Shoji; Kakoi, Hisae; Goto, Toshio (Fac. Pharm., Meijo Univ., Nagoya, Japan). J. Chem. Soc., Chem.In this article, certain chemicals are used. One of their cas registry numbers is 55779-48-1 Commun., (24), 1056-7 (English) 1976. CODEN: JCCCAT. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 12 The structure of Oplophorus luciferin (I; R = 4-HOC6H4, R1 = PhCH2, R2 = 4-HOC6H4CH2), isolated from O. spinosus and H. laevigatus, was detd. from spectral data and luminesence rates. The structure I [R = R1 = H, R2 = PrCH(OH)] proposed by I. Yamaguchi (1975) is therefore erroneous. .
