Novel matrix proteins of Pteria penguin pearl oyster shell nacre homologous to the jacalin-related β-prism fold lectins. [PDF]

open access: yesPLoS ONE, 2014
Nacreous layers of pearl oyster are one of the major functional biominerals. By participating in organic compound-crystal interactions, they assemble into consecutive mineral lamellae-like photonic crystals.

Glycan Binding Profiling of Jacalin-Related Lectins from the Pteria Penguin Pearl Shell [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
We determined the primary structures of jacalin-related lectins termed PPL3s (PPL3A, 3B, and 3C, which are dimers consisting of sequence variants α + α, α + β, β + β, respectively) and PPL4, which is heterodimer consisting of α + β subunits, isolated from mantle secretory fluid of Pteria penguin (Mabe) pearl shell. Their carbohydrate-binding properties

Diversified Carbohydrate‐Binding Lectins from Marine Resources [PDF]

open access: yesJournal of Amino Acids, Volume 2011, Issue 1, 2011., 2011
Marine bioresources produce a great variety of specific and potent bioactive molecules including natural organic compounds such as fatty acids, polysaccharides, polyether, peptides, proteins, and enzymes. Lectins are also one of the promising candidates for useful therapeutic agents because they can recognize the specific carbohydrate structures such ...

The mechanisms involved in byssogenesis in Pteria penguin under different temperatures

open access: yesScience of The Total Environment, 2023
Byssus is important for marine bivalves to adhere robustly to diverse substrates and resist environmental impacts. The winged pearl oyster, Pteria penguin, can reattach or not reattach to the same environment, which leaves the development and survival of the oyster population at risk.

An Analysis of the Cloning, Functional Analysis, and Identification of Three Cloned Digestive Enzymes Associated with Growth Traits in Haliotis diversicolor

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
The purpose of this study was to determine the effect of different feeds such as Porphyra, Laminaria japonica, Compound feed, and Gracilaria on the activities of alginate lyase, cellulase, and amylase in the digestive juice of H. diversicolor and to take their genes as candidate genes related to the growth traits of H. diversicolor. In order to provide

Embryonic and larval development of Pteria penguin (Roding, 1798) (Bivalvia: Pteriidae) [PDF]

open access: yesJournal of Molluscan Studies, 2011
This study describes the processes of embryogenesis, shell formation and larval development of the winged pearl oyster, Pteria penguin. Broodstock were induced to spawn using the standard method of thermal stimulation and fertilized eggs were incubated at a density of 50 ml−1 and a temperature of 27 ± 1°C.

Effects of air exposure time and temperature on physiological energetics and oxidative stress of winged pearl oyster (Pteria penguin)

open access: yesAquaculture Reports, 2020
The winged pearl oyster (Pteria penguin) is one of the most potential species used to produce large sized pearls. Waterless transport and nuclei implant process are two common handling practices for pearl oyster in aquaculture.
