Nucleotide sequence of the Streptococcus faecalis plasmid gene encoding the 3'5"-aminoglycoside phosphotransferase type III. 1983

P Trieu-Cuot, and P Courvalin

We have cloned in Escherichia coli and sequenced a 1489-bp DNA fragment conferring resistance to kanamycin and originating from the streptococcal plasmid pJH1. The resistance gene was located by analysis of the initiation and termination codons in an open reading frame (ORF) of 792 bp. The deduced gene product, a 3'5''-aminoglycoside phosphotransferase of type III, has an Mr of 29,200. Comparison of its amino acid sequence with those of type I (Oka et al., 1981) and type II (Beck et al., 1982) 3' phosphotransferase, from transposable elements Tn903 and Tn5, respectively, indicated a statistically significant structural relationship between these enzymes from phylogenetically remote bacterial genera. The degree of homology observed indicate that phosphotransferase type III and type I genes have diverged from a common ancestor and that the phosphotransferase type II gene has emerged more recently from the type I evolutionary pathway.

D003001	Cloning, Molecular	The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.	Molecular Cloning
D004251	DNA Transposable Elements	Discrete segments of DNA which can excise and reintegrate to another site in the genome. Most are inactive, i.e., have not been found to exist outside the integrated state. DNA transposable elements include bacterial IS (insertion sequence) elements, Tn elements, the maize controlling elements Ac and Ds, Drosophila P, gypsy, and pogo elements, the human Tigger elements and the Tc and mariner elements which are found throughout the animal kingdom.
