Plastid genomes of two brown algae, Ectocarpus siliculosus and Fucus vesiculosu...
Le Corguillé, Gildas; Pearson, G. A.; Valente, Marta; Viegas, C. S. B.; Gschloessl, Bernhard; Corre, E.; Bailly, Xavier; Peters, Akira F.Background: Heterokont algae, together with cryptophytes, haptophytes and some alveolates, possess red-algal derived plastids. The chromalveolate hypothesis proposes that the red-algal derived plastids of all four groups have a monophyletic origin resulting from a single secondary endosymbiotic event. However, due to incongruence between nuclear and plastid phylogenies, this controversial hypothesis remains und...
Gla-rich protein (GRP), a new vitamin K-dependent protein identified from sturg...
Viegas, C. S. B.; Simes, Dina; Laizé, Vincent; Williamson, M. K.; Price, P. A.; Cancela, LeonorWe report the isolation of a novel vitamin K-dependent protein from the calcified cartilage of Adriatic sturgeon (Acipenser nacarii). This 10.2-kDa secreted protein contains 16 -carboxyglutamic acid (Gla) residues in its 74-residue sequence, the highest Gla percent of any known protein, and we have therefore termed it Gla-rich protein (GRP). GRP has a high charge density (36 negative 16 positive 20 net nega...
Cloning and ontogenetic expression of the oligopeptide transporter PepT1 (Solut...
Rønnestad, I.; Gavaia, Paulo J.; Viegas, C. S. B.; Cancela, LeonorFunctional characteristics of marine fish larvae digestive system at the onset of exogenous feeding have long been a subject for discussion. Absorption of digested proteins in vertebrates has been shown to include transporter systems for single amino acids and small peptides.
Gla proteins as markers for studies of skeletal development and malformations i...
Viegas, C. S. B.; Gavaia, Paulo J.; Ortiz-Delgado, J. B.; Sarasquete, C.; Cancela, LeonorEvaluation of the onset and the development of skeletal structures during larval ontogeny of commercially important species in southern Iberia Peninsula and Mediterranean area (...) is essential for the successful production of high quality fish.
