| metabolism | comparison of growth characteristics including intracellular protein levels, RNA content, and nucleotide pool sizes between the extreme halophile Halobacterium halobium and the moderate halophile Haloferax volcanii. The differences in the metabolism of purine bases and nucleosides and the sensitivity to purine analogs between the two halobacteria are reflected in differences in purine enzyme levels | Halobacterium salinarum |
