An analysis of the approximately 12,440 base-pair sequence of the EcoRI Dhet fragment isolated from the circular episomal form of the B95-8 strain of Epstein-Barr virus is presented. This fragment contains the covalently joined ends of the intracellular episomal form of the molecule. In the viral capsid the DNA is linear and the joining is mediated via the terminal repeated DNA. Four copies of tandem repeated DNA were present in this clone, three with a repeat size of 538 and one of 523. The positions of a number of possible protein coding regions and transcription signals are discussed. In particular a possible spliced coding region for an approximately 45,000 Mr protein expressed in latently infected transformed cells is proposed. The predicted protein sequence contains hydrophobic regions separated by charged amino acids reminiscent of a membrane protein.
