Structure and phospholipase function of peroxiredoxin 6: identification of the catalytic triad and its role in phospholipid substrate binding1

Journal of Lipid Research, 2007
Peroxiredoxin 6 (Prdx6) is a bifunctional protein with glutathione peroxidase and phospholipase A2 (PLA2) activities, and it alone among mammalian peroxiredoxins can hydrolyze phospholipids.

Genetic Evidence of Multiple and Diverse Range Expansion Events From an Outbreak of the Crown‐of‐Thorns Seastar, Acanthaster Cf. Solaris on a Subtropical Reef

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study examines the population genetics of a Crown of Thorns seastar (Acanthaster cf. solaris) outbreak on a subtropical coral reef. We demonstrate that this population originated from larval connectivity via the East Australian Current from the Great Barrier Reef, with high genomic connectivity indicating substantial risk of future outbreaks as ...

The phospholipase A2 activity of peroxiredoxin 6 [S]

Journal of Lipid Research, 2018
Peroxiredoxin 6 (Prdx6) is a Ca2+-independent intracellular phospholipase A2 (called aiPLA2) that is localized to cytosol, lysosomes, and lysosomal-related organelles.

Structural insights into transition‐metal–aminodiphosphine (PNP) complexes bearing [MCln(PNP)2] (M = Co, Ru, Cr or Mo; n = 1 or 2) cores in the solid state

Acta Crystallographica Section C, Volume 81, Issue 12, Page 694-701, December 2025.
The molecular structures of two novel cobalt aminodiphosphine (PNP) complexes are reported, featuring variation in the N‐atom substituent. A Cambridge Structural Database (CSD) survey, along with a noncovalent interaction (NCI) analysis of the analogous [TMCln(PNP)2] (where TM = transition metal and n = 1 or 2) core, revealed an inverse correlation ...

Metastable spin textures and Nambu-Goldstone modes of a ferromagnetic spin-1 Bose-Einstein condensate confined in a ring trap

, 2014
We investigate the metastability of a ferromagnetic spin-1 Bose-Einstein condensate confined in a quasi-one-dimensional rotating ring trap by solving the spin-1 Gross-Pitaevskii equation. We find analytical solutions that exhibit spin textures.
