31 kDa metal enriched copper/zinc superoxide dismutase obtained from the haemolymph of the shellfish Crassostrea gigas

摘要

Disclosed is a protein readily extracted from the pacific oyster Crassostrea gigas exhibiting metal ion binding activity and can be formulated into bioremediation compositions, foodstuffs and nutraceuticals. The protein has a molecular weight of approximately 20 kDa and an amino acid sequence selected from: a) TAXNEANVNIYLHLSDDEDSNYENS (N-terminus) (SEQ ID NO:1) b) EPNAFMPGNLHHRV (SEQ ID NO:2) c) EHGXDTIGEL (SEQ ID NO:3)
