Special Issue Information

Dear Colleagues,

Ice-binding proteins are a group of proteins that have affinity for ice. Antifreeze proteins, the most commonly-known terminology for this kind of protein, are a misnomer since they are actually a subset of ice-binding protein and some, not all, ice-binding proteins function as a biological antifreeze in physiological concentrations. In this Special Issue, we would like to use “ice-binding proteins” to include any proteins that have affinity for ice, such as antifreeze proteins, ice nucleation proteins, ice-recrystallization inhibition proteins, and ice-interacting proteins.

Since the fish antifreeze proteins were first identified in the late 1960s, the number of ice-binding proteins identified from marine organisms has been continuously increasing. Currently, ice-binding proteins are found in bacteria, fungi, microalgae, and crustaceans inhabiting cold environments. Marine ice-binding proteins seem to possess characteristic ice-binding sites, despite their diversity in primary and tertiary structures. The ice-binding affinity is well manifested in their properties: Thermal hysteresis and ice-recrystallization inhibition. In addition, some ice-binding proteins appear to interact with biological membranes. These properties are of biotechnological interest for cryopreservation of valuable biological resources, such as stem cells.

This Special Issue, “Marine Ice-Binding Proteins and Their Mimetics: Structure, Function, and Applications”, of Marine Drugs will cover, but is not limited to, reviews and recent results regarding the isolation and characterization of new marine ice-binding genes and proteins, structure determination, and application of ice-binding proteins, mimetic peptides and/or peptoids in various fields, such as cryopreservation and hypothermic storage.

Antifreeze proteins (AFPs) protecting the cells against freezing are produced in response to extremely low temperatures in diverse psychrophilic organisms, and they are encoded by multiple gene families. The AFP of Antarctic marine diatom Chaetoceros neogracile is reported in our previous research, but like other microalgae, was considered to probably have additional genes coding AFPs. In this paper, we reported the cloning and characterization of additional AFP gene from C. neogracile (Cn-isoAFP). Cn-isoAFP protein is 74.6% identical to the previously reported Cn-AFP. The promoter sequence of Cn-isoAFP contains environmental stress responsive elements for cold, thermal, and high light conditions. Cn-isoAFP transcription levels increased dramatically when cells were exposed to freezing (−20 °C), thermal (10 °C), or high light (600 μmol photon m−2 s−1) stresses. The thermal hysteresis (TH) activity of recombinant Cn-isoAFP was 0.8 °C at a protein concentration of 5 mg/mL. Results from homology modeling and TH activity analysis of site-directed mutant proteins elucidated AFP mechanism to be a result of flatness of B-face maintained via hydrophobic interactions.
