Abstract:
The sequence of genes encoding extracellular amylopullulanase and putative maltodextrin ATP binding cassette (ABC) transporter of a hyperthermophilic archaeon, Thermococcus litoralis, was determined. The mdxK gene, which encodes an ATPase subunit of the putative maltodextrin ABC transporter, has extraordinarily high similarity with the malK gene, which encodes an ATPase subunit of trehalose/maltose ABC transporter of the same organism. DNA sequence comparison revealed that the malK gene was generated through the duplication of the mdxK gene before lateral gene transfer of the mal gene cluster from T. litoralis to Pyrococcus furiosus.
