Bottom-up synthesis of hyaluronan and its derivatives via enzymatic polymerization: direct incorporation of an amido functional group.

abstract：:Antifreeze glycoproteins (AFGPs) are a subclass of biological antifreezes found in deep sea Teleost fish. These compounds have the ability to depress the freezing point of the organism such that it can survive the subzero temperatures encountered in its environment. This physical property is very attractive for the cr...
