Cruz, J.R. Magalhães & C.P. Von Dietrich developed isolated rabbit ear method for hemostasis in vivo (1962) Showed the role that spermine and spermidine play in muscle relaxation (1967-8) First found a Ca2+ pump in tissues others than skeletal muscle and showed acetyl phosphate as substrate by sarco/endoplasmic reticulum Ca2+-ATPases Discovered the formation of low energy phosphoenzyme (1973) independently of P.D. Boyer With H. Masuda demonstrated the occurrence of phosphorylation (ATP production) without a gradient (1973) Demonstrated that the same chemical species can be of high and low energy depending on environment that around it (1970s), today a basic concept in cellular thermodynamics With A.L. Vianna proposed the basic catalytic cycle of the Ca2+-ATPase (1979) Proposed that the change in energy of hydrolysis that occurs during the process of energy transduction was indeed relative to a change in solvent structure around reactants and products at the catalytic site of enzymes (1989-93) Proposed that catalytic site of mitochondrial ATP synthase undergoes a hydrophobic-hydrophilic transition during oxidative phosphorylation Indicated that Ca2+-ATPase is able to handle the energy derived from ATP hydrolysis in such a way as to determine the amount used for Ca2+ transport and the amount that is dissipated as heat With L.A. Ketzer, R.M. da Costa, I. R. de Andrade & M.
