Molecular characterization and expression analysis of extracellular copper/zinc superoxide dismutase (ecCuZnSOD) from oriental river prawn, Macrobrachium nipponense

► We cloned an extracellular CuZnSOD from Macrobrachium nipponense (MnECSOD). ► We analyzed the characterisation of MnECSOD. ► The expression of MnECSOD in various tissues was investigated. ► MnECSOD expression profiles were studied after challenged with A. hydrophila.
