报告摘要:

  Crawfish are freshwater lobster-like crustaceans, found in many warm regions. Their digestive fluid contains a very unique metallo-endopeptidase, astacin, not found in the digestive systems of other species to date. The astacin peptidase family is comprised many analogous proteins of diverse functions, including fish hatching enzyme, sea urchin developing BP10 protease, hydra regeneration enzyme, and bone morphogenetic protease in developmental biology, and a microbial protease as a virulence factor.

The active center of astacin protease family is collagenase like, but with a coordinated tyrosine only unique to this family. Thus, the hydrolytic mechanism must be very unique among hydrolases. Whether or not and how the unique mechanism found its way in developmental biology is an interesting story to be revealed. How broad this protease family distribute in the living systems awaits future discoveries. From crayfish, to fish hatching, sea urchin development, and hydra regeneration, and to developmental biology and microbiology, the rivers and oceans provide endless resources.
