Multiple replication origins with diverse control mechanisms in Haloarcula hispanica
The use of multiple replication origins in archaea is not well understood. In particular, little is known about their specific control mechanisms. Here, we investigated the active replication origins in the three replicons of a halophilic archaeon, Haloarcula hispanica, by extensive gene deletion, DNA mutation and genome-wide marker frequency analyses. We revealed that individual origins are sp...
متن کاملAmino acid biosynthesis in the halophilic archaeon Haloarcula hispanica.
Biosynthesis of proteinogenic amino acids in the extremely halophilic archaeon Haloarcula hispanica was explored by using biosynthetically directed fractional 13C labeling with a mixture of 90% unlabeled and 10% uniformly 13C-labeled glycerol. The resulting 13C-labeling patterns in the amino acids were analyzed by two-dimensional 13C,1H correlation spectroscopy. The experimental data provided e...
متن کاملAn improved transposon for the halophilic archaeon Haloarcula hispanica.
An improved transposon (ThD73) for Haloarcula hispanica is described. Based on the halobacterial insertion sequence ISH28, it showed little target sequence specificity but was biased toward a lower G+C content. Twenty randomly selected ThD73 mutants were analyzed, and the DNA flanking their insertions revealed several recognizable sequences, including two (unrelated) ISH elements.
متن کاملHis1, an archaeal virus of the Fuselloviridae family that infects Haloarcula hispanica.
A novel archaeal virus, His1, was isolated from hypersaline waters in southeastern Australia. It was lytic, grew only on Haloarcula hispanica (titers of up to 10(11) PFU/ml), and displayed a lemon-shaped morphology (74 by 44 nm) previously reported only for a virus of the extreme thermophiles (SSV1). The density of His1 was approximately 1.28 g/ml, similar to that of SSV1 (1.24 g/ml). Purified ...
متن کاملNew, closely related haloarchaeal viral elements with different nucleic Acid types.
During the search for haloarchaeal viruses, we isolated and characterized a new pleomorphic lipid-containing virus, Haloarcula hispanica pleomorphic virus 1 (HHPV-1), that infects the halophilic archaeon Haloarcula hispanica. The virus contains a circular double-stranded DNA genome of 8,082 bp in size. The organization of the genome shows remarkable synteny and amino acid sequence similarity to...
