摘要
A detailed physical map of the BK virus (MM strain) genome has been constructed with respect to the cleavage sites of 11 different restriction enzymes. The enzymes cut BKV(MM) DNA at 61 specific sites whose locations have been determined. Preliminary nucleotide sequence was carried out in the region from 0.70 - 0.75 map positions on BKV(MM) DNA. An 80% homology was found at 0.714 - 0.744 map positions on BKV(MM) DNA with 0.722 - 0.752 map positions on simian virus 40 DNA. This region of simian virus 40 DNA codes for the synthesis of the leader sequence of late mRNA.
