The tight binding of Cu and Zn ions to superoxide dismutase 1 (SOD1) maintains the protein stability, associated with amyotrophic lateral sclerosis (ALS). Yet, the quantitative studies remain to be explored for the metal-binding affinity of wild-type

Prostaglandins, well-known lipid mediators in vertebrate animals, have also shown to play certain regulatory roles in insects and other arthropods acting on reproduction, immune system and ion transport. However, knowledge of their biosynthetic pathw

The conversion of fatty acid hydroperoxides to allene epoxides is catalysed by a cytochrome P450 in plants. In contrast, in the coral Plexaura homomalla, a catalase-related hemoprotein fused to the lipoxygenase (LOX) was found to function as an allen

Formation of amyloid-like fibrils by insulin was studied at different insulin concentrations, pH and temperatures. At low pH (pH 2.5) the insulin fibrillization occurred only at high (>10 μM) peptide concentrations, whereas at physiological pH value

It has been known for 30 years that the gorgonian coral Plexaura homomalla contains either 15S- or 15R-configuration prostaglandins (PGs), depending on its location in the Caribbean. Recently we showed that the 15R-PGs in the R-variety of P. homomall

The highest concentrations of prostaglandins in nature are found in the Caribbean gorgonian Plexaura homomalla . Depending on its geographical location, this coral contains prostaglandins with typical mammalian stereochemistry (15 S -hydroxy) or the

In vertebrates, the synthesis of prostaglandin hormones is catalyzed by cyclooxygenase (COX)-1, a constitutively expressed enzyme with physiological functions, and COX-2, induced in inflammation and cancer. Prostaglandins have been detected in high c

Certain corals are rich natural sources of prostaglandins, the metabolic origin of which has remained undefined. By analogy with the lipoxygenase/allene oxide synthase pathway to jasmonic acid in plants, the presence of (8R)-lipoxygenase and allene o

A novel natural E-prostaglandin - 1a-1b-dihomo-2,3 didehydro-PGE2 (1) was isolated from ram seminal vesicles and its structure was elucidated by MS and NMR analysis.
