Here we report the characterization of the type-1 isopentenyl diphosphate isomerase derived from Halobacterium sp. NRC-1. The expressed purified enzyme showed maximum isomerase activity in the presence of 1 M NaCl at 37 degrees C at pH 6.0. This type-1 enzyme appears to be the first for which the Co2+ ion is required for activity.
In a study of a lake having a higher concentration of salts than the Dead Sea, all of the heterotrophic bacteria isolated were aerobes; no strictly anaerobic strains were found. Ninety percent of the strains were euryhalines and ten percent were strict halophiles. The extreme halophiles belonged to the species Halobacterium trapanicum and Halococcus morrhuae.
We report the complete sequence of the 4,274,642-bp genome of Haloarcula marismortui, a halophilic archaeal isolate from the Dead Sea. The genome is organized into nine circular replicons of varying G+C compositions ranging from 54% to 62%. Comparison of the genome architectures of Halobacterium sp. NRC-1 and H. marismortui suggests a common ancestor for the two organisms and a genome of signif...
