    ACE2 purified from failing human heart was found to form a complex with integrin beta1 by immunoprecipitation, Western blotting, activity assay, and ESI tandem mass spectroscopy. The ACE2/integrin complex showed a Km of 6.8 microM and a Vmax of 2.13 pmol/min/microl purified enzyme. Activity was optimal at pH 7.5 with Ang II substrate.
