Wild-type sequences and corresponding scrambled versions of EBV-encoded miRNAs.

#) The sequence of miR-BART4* is present in all 2089-derived mutant EBVs but its pre-miRNA cannot form the necessary stem of the hairpin structure in ΔmirALL because the sequence of the 5′ arm is scrambled as in miR-BART4. +) The sequence of miR-BART5 is present in prototype 2089 EBV but due to the deletion in the parental B95.8 EBV strain it cannot fold into the pre-miRNA hairpin structure and is therefore not processed to the mature miR-BART5 even in the prototype 2089 EBV and B95.8 strains.
