rDNA corresponding to an endosymbiotic bacteria associated with
Ecteinascidia turbinata has been identified. The bacterium appears to be
responsible for the biosynthesis of ecteinascidin compounds. The 16S rDNA
sequence corresponding to Candidatus Endoecteinascidia frumentensis SEQ
ID NO: 1 has been deposited in GeneBank with the accession number
AY054370.
