Study on the Behavior of the Tenebrio Molitor Antifreeze Proteins during the Adsorption Process of Gas Hydrates
Molecular dynamics simulation was used to calculate and analyze the local structural changes of the Tenebrio molitor antifreeze proteins during the adsorption process with methane hydrates.Studies have shown that when threonine 4 at the hydrate binding site is close to the sur-face of methane hydrate,its position will change to adapt to the cage structure of the hydrate,replace methane molecules and bind to the surface of the hydrate,and promote other threonines to be close to the hydrate,and finally the antifreeze protein of Mealworm is adsorbed on the hydrate,thus inhibiting the growth of ice solids.The results of this study have reference significance for the research and development of biodegradable natural product-based hydrate inhibitors.
