Impairment of IGF-I gene splicing and MGF expression associated with muscle wasting.

An aminopeptidase was purified from bovine skeletal muscle by ammonium sulfate fractionation and by successive chromatographies of DEAE-cellulose, Sehacryl S-200, phenyl-sepharose CL-4B, hydroxyapatite and Hi-Trap chelating HP columns. The aminopeptidase was purified about 14-fold over the crude extract with a yield of 1.0% activity. The molecular mass of the enzyme was found to be 58 kDa on SDS-PAGE. The enzyme activity was enhanced by the addition of some anions, such as Cl-, NO3- and SCN-, which is the most unique property of this enzyme. While, the activity was strongly inhibited by bestatin, PMSF and puromycin, suggesting that it was a serine protease. In addition, this enzyme was identical with leukotriene (LT) A4 hydrolase, converting LTA4 to LTB4. (c) 2005 Published by Elsevier Ltd.
