    • ATPase and ADPase activities in synovial membrane of equine metacarpophalangeal joint 
      Jiménez, Paula; García Nannig, Lorena; Adarmes, H.; González, E.; Valenzuela, M. A. (2002)
      ATPase and ADPase activities capable of hydrolyzing nucleoside di- and triphosphates in the presence of Ca2+ are present in synovial membrane of metacarpophalangeal joint mainly associated to membrane fractions. These ...
    • Changes in apyrase activity in uterus and mammary gland during the lactogenic cycle 
      Valenzuela, M. A.; Collados, L.; Kettlun, A. M.; Mancilla, M.; Puente, J.; Aranda, E.; Chayet, L.; Alvarez, A.; Traverso Cori, A. (1992)
      1. 1. The purpose of this present research was to explore the possible roles of ATP-diphosphohydrolase (apyrase) in two tissues with high energetic demands during cell proliferation and differentiation. 2. 2. Changes in ...
    • Studies on ATP-diphosphohydrolase nucleotide-binding sites by intrinsic fluorescence 
      Kettlun, A. M.; Espinosa, V.; Zanocco, A.; Valenzuela, M. A. (Associacao Brasileira de Divulgacao Cientifica, 2000)
      Potato apyrase, a soluble ATP-diphosphohydrolase, was purified to homogeneity from several clonal varieties of Solanum tuberosum. Depending on the source of the enzyme, differences in kinetic and physicochemical properties ...
