Shuttle vectors for the archaebacterium Halobacterium volcanii

Abstract

Progress in archaebacterial molecular biology requires tools for genetic analysis. We describe vectors that can be selected and maintained in either Halobacterium volcanii or Escherichia coli. A genetic determinant for resistance to the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor mevinolin was isolated by "shotgun cloning" into a derivative of the endogenous H. volcanii plasmid pHV2, to form pWL2, which transforms sensitive H. volcanii to mevinolin resistance at high frequency. The resistance determinant, portions of pHV2, and an ampicillin- and tetracycline-resistance-conferring pBR322 derivative, pAT153, were ligated together to form the shuttle vectors pWL101 and pWL102. We describe conditions for the use of these vectors and provide preliminary definition of regions essential for drug resistance and for plasmid replication and maintenance.
