    • Adenosine diphosphate glucose pyrophosphatase: a plastidial phosphodiesterase that prevents starch biosynthesis 

      Rodríguez López, Milagros Upna; Baroja Fernández, Edurne Upna; Zandueta Criado, Aitor Upna; Pozueta Romero, Javier Upna (National Academy of Sciences, 2000)   Artículo / Artikulua  OpenAccess
      A distinct phosphodiesterasic activity (EC 3.1.4) was found in both mono- and dicotyledonous plants that catalyzes the hydrolytic breakdown of ADPglucose (ADPG) to produce equimolar amounts of glucose-1-phosphate and AMP. ...
    • Adenosine diphosphate sugar pyrophosphatase prevents glycogen biosynthesis in Escherichia coli 

      Moreno Bruna, Beatriz Upna; Baroja Fernández, Edurne Upna; Muñoz Pérez, Francisco José Upna; Bastarrica Berasategui, Ainara Upna; Zandueta Criado, Aitor Upna; Rodríguez López, Milagros Upna; Lasa Uzcudun, Íñigo Upna; Akazawa, Takashi; Pozueta Romero, Javier Upna (National Academy of Sciences, 2001)   Artículo / Artikulua  OpenAccess
      An adenosine diphosphate sugar pyrophosphatase (ASPPase, EC 3.6.1.21) has been characterized by using Escherichia coli. This enzyme, whose activities in the cell are inversely correlated with the intracellular glycogen ...
    • Most of ADP-glucose linked to starch biosynthesis occurs outside the chloroplast in source leaves 

      Baroja Fernández, Edurne Upna; Muñoz Pérez, Francisco José Upna; Zandueta Criado, Aitor Upna; Morán Zorzano, María Teresa Upna; Viale, Alejandro M. Upna; Alonso Casajús, Nora Upna; Pozueta Romero, Javier Upna (National Academy of Sciences, 2004)   Artículo / Artikulua  OpenAccess
      Sucrose and starch are end products of two segregated gluconeogenic pathways, and their production takes place in the cytosol and chloroplast of green leaves, respectively. According to this view, the plastidial ADP ...
