- ItemATPASE-ADPASE ACTIVITIES OF RAT PLACENTAL TISSUE(1991) PIEBER, M; VALENZUELA, MA; KETTLUN, AM; MANCILLA, M; ARANDA, E; COLLADOS, L; TRAVERSOCORI, A1. Calcium-stimulated ATPase-ADPase activities were studied in a microsomal fraction of rat placental tissue.
- ItemCHANGES IN APYRASE ACTIVITY IN UTERUS AND MAMMARY-GLAND DURING THE LACTOGENIC CYCLE(1992) VALENZUELA, MA; COLLADOS, L; KETTLUN, AM; MANCILLA, M; LARA, H; PUENTE, J; ARANDA, E; CHAYET, L; ALVAREZ, LCA; TRAVERSOCORI, A1. 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.
- ItemHUMAN PLACENTAL ATP-DIPHOSPHOHYDROLASE - BIOCHEMICAL-CHARACTERIZATION, REGULATION AND FUNCTION(1994) KETTLUN, AM; ALVAREZ, A; QUINTAR, R; VALENZUELA, MA; COLLADOS, L; ARANDA, E; BANDA, A; CHAYET, L; CHIONG, M; MANCILLA, M; TRAVERSOCORI, A1. Kinetic and physico-chemical studies on human placental microsomal fraction confirmed that the ATPase and ADPase activities detected in this fraction correspond to the enzyme ATP-diphosphohydrolase or apyrase (EC 3.6.1.5). These include substrate specificity, and coincident M(r) and pI values of both ATPase-ADPase activities.
