“…Some strains are able to grow at 25-55°C but required at least 2.5 M NaCl for growth. Hypotonic treatment with less than 2 M NaCl caused cell lysis [91]. Here again, when we performed multiple amino acid alignments no meaningful information could be obtained and LOX iron ligands were not conserved.…”

Leukotrienes are pro-inflammatory lipid mediators, which are biosynthesized via the lipoxygenase pathway of the arachidonic acid cascade. Lipoxygenases form a family of lipid peroxidizing enzymes and human lipoxygenase isoforms have been implicated in the pathogenesis of inflammatory, hyperproliferative (cancer) and neurodegenerative diseases. Lipoxygenases are not restricted to humans but also occur in a large number of pro- and eucaryotic organisms. Lipoxygenase-like sequences have been identified in the three domains of life (bacteria, archaea, eucarya) but because of lacking functional data the occurrence of catalytically active lipoxygenases in archaea still remains an open question. Although the physiological and/or pathophysiological functions of various lipoxygenase isoforms have been studied throughout the last three decades there is no unifying concept for the biological importance of these enzymes. In this review we are summarizing the current knowledge on the distribution of lipoxygenases in living single and multicellular organisms with particular emphasis to higher vertebrates and will also focus on the genetic diversity of enzymes and receptors involved in human leukotriene signaling.

An extremely halophilic archaeon, strain PJ61 T , was isolated from a subterranean rock salt of Yuanyongjing Salt Mine, Yunnan, China. Colonies were pale, smooth, convex, and round (1.0-2.0 mm in diameter) on nutrient agar plates. Cells of strain PJ61 T were spherical or oval , stained Gram-negative, and were non-motile. Optimal growth was observed with 3.4 M NaCl and at 38 C in aerobic conditions. Mg 2+ was required for growth. Phylogenetic analysis based on 16S rRNA gene sequence similarities showed that strain PJ61 T belonged to the genus Halorubrum and was closely related to Halorubrum laminariae R60 T (98.3 % 16S rRNA gene sequence similarity), Halorubrum salinum GX71 T (98.2 %) and other species of the genus Halorubrum (<98 %). Sequence similarities of rpoB¢ gene and ef-2 gene between strain PJ61 T and the species of the genus Halorubrum also showed that strain PJ61 T was closely related to strain Halorubrum salinum GX71 T (93.4 % for rpoB¢and 94.8 % for ef-2). The DNA-DNA relatedness between strains PJ61 T and Halorubrum laminariae R60 T was 33±0.5 %, while it was 37±0.4 % for Halorubrum salinum GX71 T . The DNA G+C content of strain PJ61 T was 65.1 mol%. The major polar lipids of strain PJ61 T consisted of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, phosphatidylglycerol sulfate and sulfated mannosyl glucosyl diether. The phenotypic, chemotaxonomic and phylogenetic properties suggest that strain PJ61 T represents a novel species of the genus Halorubrum, for which the name Halorubrum pallidum sp. nov. is proposed. The type strain is PJ61 T (=CGMCC 1.15212 T =JCM 30955 T ).
