Characterization and Function of the First Antibiotic Isolated from a Vent Organism: The Extremophile Metazoan Alvinella pompejana
The emblematic hydrothermal worm Alvinella pompejana is one of the most thermo tolerant animal known on Earth. It relies on a symbiotic association offering a unique opportunity to discover biochemical adaptations that allow animals to thrive in such a hostile habitat. Here, by studying the Pompeii worm, we report on the discovery of the first antibiotic peptide from a deep-sea organism, namely...
متن کاملNew Insights into the Evolution of Metazoan Tyrosinase Gene Family
Tyrosinases, widely distributed among animals, plants and fungi, are involved in the biosynthesis of melanin, a pigment that has been exploited, in the course of evolution, to serve different functions. We conducted a deep evolutionary analysis of tyrosinase family amongst metazoa, thanks to the availability of new sequenced genomes, assessing that tyrosinases (tyr) represent a distinctive feat...
متن کاملCharacterization of a Y-Family DNA Polymerase eta from the Eukaryotic Thermophile Alvinella pompejana
Human DNA polymerase η (HsPolη) plays an important role in translesion synthesis (TLS), which allows for replication past DNA damage such as UV-induced cis-syn cyclobutane pyrimidine dimers (CPDs). Here, we characterized ApPolη from the thermophilic worm Alvinella pompejana, which inhabits deep-sea hydrothermal vent chimneys. ApPolη shares sequence homology with HsPolη and contains domains for ...
متن کاملThermal selection of PGM allozymes in newly founded populations of the thermotolerant vent polychaete Alvinella pompejana.
Alvinella pompejana lives on the top of chimneys at deep-sea hydrothermal vents of the East Pacific Rise. It is thought to be one of the most thermotolerant and eurythermal metazoans. Our experimental approach combines methods of population genetics and biochemistry, considering temperature as a potential selective factor. Phosphoglucomutase (Pgm-1 locus) is one of the most polymorphic loci of ...
متن کاملLiving in a hot redox soup: antioxidant defences of the hydrothermal worm Alvinella pompejana
The hydrothermal Pompeii worm Alvinella pompejana lives very close to the walls of black smokers and is therefore exposed to high-temperature venting fluid containing high concentrations of sulphides and metals. The highly aerobic metabolism of these annelids, together with these extreme physico-chemical conditions, theoretically accelerates redox processes in and around the worm, potentially i...
