Nucleotide sequence and genetic map of the 16-kb vaccinia virus HindIII D fragment.
We have determined the nucleotide sequence of the 16,059-bp HindIII D fragment from vaccinia virus strain WR. Translation in all 6 reading frames reveals a set of 22 open reading frames (ORFs), which are capable of encoding proteins ranging from 61 to 844 amino acids in length. With one exception, ORF 12, we have divided them into two primary sets according to their size. The minor group contains eight members ranging in length from 61 to 84 amino acids. The major group has thirteen members varying from 146 to 844 amino acids in length, and, in addition, due to its location on the DNA, one small ORF, 61 amino acids long. The neighboring major ORFs are closely packed along the DNA, being separated by 42 or fewer base pairs. In several instances the ends of adjoining ORFs overlap for up to 11 triplet codons. In three cases, 1 or 2 bases are shared between translation start and stop signals in adjacent ORFs. Regions of both strands of the DNA are transcribed. Two sets of temperature-sensitive mutations, totaling 17, which map to the HindIII D fragment, have been combined into eight complementation groups. The results of marker rescue analysis map one or more member of each group to a site in the HindIII D fragment within a defined open reading frame.
