We have cloned and expressed two full-length cDNAs that encode two distinct Renilla Coel-STs by combining de novo peptide sequencing with transcriptome analysis. These were both shown to convert coelenterazine sulfate to coelenterazine. The sulfotransferase is a member of the Pfam, PF00685. The recombinant form of Coel-ST now makes practicable a very sensitive PAP assay described by Stanley in 1975 and refined further by Anderson in 1978.
