Properties of trehalase from the muscles of fresh water prawn Macrobrachium lamarrei

Summary The trehalase from the extramitochondrial fraction of abdominal and thoracic muscles of Macrobrachium lamarrei was purified to give a 12.85fold increase in specific activity. Its optimum pH was 6.0, K_m value was 2.85 mM and had a mol.wt around 120,000. Tris HCl buffer inhibited the enzyme activity by 21.7%.I am thankful to Prof. R. Rakshpal and Dr Padma Saxena for guidance and to University Grants commission, India, for the award of a Junior Research Fellowship
