The complete nucleotide sequence of the structural gene TOP2 of yeast DNA topoisomerase II
G Giaever, R Lynn, T Goto and JC Wang
The nucleotide sequence of the gene TOP2 encoding DNA topoisomerase II of
the yeast Saccharomyces cerevisiae has been determined. The entire coding
sequence of the gene lies within an open reading frame, and there are 1429
amino acids in the single polypeptide protein if translation is assumed to
start at the first ATG in this frame. The calculated subunit and molecular
mass of the enzyme is 164,000 and 328,000 daltons, respectively. The
transcriptional starts of the gene and a polyadenylation site of the
message have also been mapped.
