Abstract

The nucleotide sequence of the gene (tnpA) which codes for the transposase of transposon Tn501 has been determined. It contains an open reading frame for a polypeptide of Mr = 111,500, which terminates within the inverted repeat sequence of the transposon. The reading frame would be transcribed in the same direction as the mercury-resistance genes and the tnpR gene. The amino acid sequence predicted from this reading frame shows 32% identity with that of the transposase of the related transposon Tn3. The C-terminal regions of these two polypeptides show slightly greater homology than the N-terminal regions when conservative amino acid substitutions are considered. With this sequence determination, the nucleotide sequence of Tn501 is fully defined. The main features of the sequence are briefly presented.
