Abundance of integrons in halophilic bacteria.

Integrons are genetic platforms used for expressing open reading frames (ORFs) arranged in gene cassettes. Excision and integration of gene cassettes are controlled by their associated integron integrase (IntI). Using IntegronFinder software, we analyzed all complete halophilic genomes available in the HaloDom database, along with selected partial halophilic genomes.

Red Sea Atlantis II brine pool nitrilase with unique thermostability profile and heavy metal tolerance.

Background: Nitrilases, which hydrolyze nitriles in a one-step reaction into carboxylic acids and ammonia, gained increasing attention because of the abundance of nitrile compounds in nature and their use in fine chemicals and pharmaceutics. Extreme environments are potential habitats for the isolation and characterization of extremozymes including nitrilases with unique resistant properties. The Red Sea brine pools are characterized by multitude of extreme conditions.
