    • Differences in nucleotide-binding site of isoapyrases deduced from tryptophan fluorescence 
      Espinosa, Victoria; Kettlun, Ana María; Zanocco Loyola, Antonio; Cardemil, E.; Valenzuela, A. M. (PERGAMON-ELSEVIER SCIENCE LTD, 2003-05)
      Comparative studies of intrinsic and extrinsic fluorescence of apyrases purified from two potato tuber varieties (Pimpernel and Desiree) were performed to determine differences in the microenvironment of the nucleotide ...
    • Fluorescence studies of ATP-diphosphohydrolase from Solanum tuberosum var. Desiree 
      Espinosa, Victoria; Kettlun, Ana María; Zanocco Loyola, Antonio; Cardemil, E.; Valenzuela Pedevila, María Antonieta (PERGAMON-ELSEVIER SCIENCE LTD, 2000-08)
      Chemical modification of potato apyrase suggests that tryptophan residues are close to the nucleotide binding site. K-d values (+/- Ca2+) for the complexes of apyrase with the non-hydrolysable phosphonate adenine nucleotide ...
