Biophysical characterization of the structural stability of Helix lucorum hemocyanin

Biotechnology & Biotechnological Equipment, 2021
The structural stability of the hеmocyanin purified from the hеmolymph of gаrden snаils Helix lucorum (HlH) was investigated by means of far-UV circular dichroism (CD), differential scanning calorimetry (DSC) and transmission electron microscopy (TEM ...

Cryo-EM structure of isomeric molluscan hemocyanin triggered by viral infection. [PDF]

PLoS ONE, 2014
Hemocyanins (Hcs) of arthropods and mollusks function not only as oxygen transporters, but also as phenoloxidases (POs). In invertebrates, PO is an important component in the innate immune cascade, where it functions as the initiator of melanin synthesis,

Protein-Level Evidence of Novel β-Type Hemocyanin and Heterogeneous Subunit Usage in the Pacific Whiteleg Shrimp, Litopenaeus vannamei

Frontiers in Marine Science, 2019
The functional diversity of crustacean hemocyanins is broad, encompassing O2 delivery, innate immune response, metabolite storage, and osmolyte balance, all in a heterogeneous protein structure.

X-ray crystallographic studies on structure and fucntion of hemocyanins. [PDF]

, 1993
Hemocyanin is the oxygen transport pigment in many arthropods and molluscs. In this respect, hemocyanin has the same function as hemoglobin has in many other organisms.

Calorimetric Study of Helix aspersa Maxima Hemocyanin Isoforms

Journal of Analytical Methods in Chemistry, 2018
The thermal unfolding of hemocyanin isoforms, β-HaH and αD+N-HaH, isolated from the hemolymph of garden snails Helix aspersa maxima, was studied by means of differential scanning calorimetry (DSC). One transition, with an apparent transition temperature (

OsCPK12‐OsATPD1 Module Regulates Photosynthetic Acclimation to Light Stress in Rice

Advanced Science, EarlyView.
OsCPK12 interacts and phosphorylates OsAtpD1 at Ser8 in its transit peptide. This phosphorylation promote its chloroplast translocation, thereby maintaining ATP synthase activity and proton gradient (ΔpH) homeostasis and regulating photosynthetic acclimation, photoprotection, and repair under light stress.

Adaptive Immunity in Marsupials

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Comparison of the marsupial and eutherian adaptive immune systems. ABSTRACT Marsupials diverged from eutherian mammals 125–160 million years ago. Although evolutionarily distinct, both groups of mammals can produce complex adaptive immune responses to antigens with several key differences.

Chemically Modified Hemocyanins with Enhanced Antibreast Cancer Activities

Proceedings, 2019
Some cancer cells hyperexpress folate receptors (FR); therefore, folate-derivatized deliverysystems are applied for a selective delivery of chemotherapeutics. [...]
