Tryptophan 54-64 apyrase Solanum tuberosum 32-39 11014304-3 2000 Kd values (+/- Ca2+) for the complexes of apyrase with the non-hydrolysable phosphonate adenine nucleotide analogues, adenosine 5"-(beta,gamma-methylene) triphosphate and adenosine 5"-(alpha,beta-methylene) diphosphate, were obtained from quenching of the intrinsic enzyme fluorescence. phosphonate adenine nucleotide 76-106 apyrase Solanum tuberosum 42-49 11014304-3 2000 Kd values (+/- Ca2+) for the complexes of apyrase with the non-hydrolysable phosphonate adenine nucleotide analogues, adenosine 5"-(beta,gamma-methylene) triphosphate and adenosine 5"-(alpha,beta-methylene) diphosphate, were obtained from quenching of the intrinsic enzyme fluorescence. 5'-adenylyl (beta,gamma-methylene)diphosphonate 118-166 apyrase Solanum tuberosum 42-49 11014304-3 2000 Kd values (+/- Ca2+) for the complexes of apyrase with the non-hydrolysable phosphonate adenine nucleotide analogues, adenosine 5"-(beta,gamma-methylene) triphosphate and adenosine 5"-(alpha,beta-methylene) diphosphate, were obtained from quenching of the intrinsic enzyme fluorescence. alpha,beta-methyleneadenosine 5'-diphosphate 171-218 apyrase Solanum tuberosum 42-49 11014304-5 2000 1,N6-ethenoadenosine triphosphate and 1,N6-ethenoadenosine diphosphate) were hydrolysed by apyrase in the presence of Ca2+, indicating binding to the active site. 1,n6-ethenoadenosine triphosphate 0-33 apyrase Solanum tuberosum 91-98 11014304-5 2000 1,N6-ethenoadenosine triphosphate and 1,N6-ethenoadenosine diphosphate) were hydrolysed by apyrase in the presence of Ca2+, indicating binding to the active site. 1,N(6)-ethenoadenosine diphosphate 38-70 apyrase Solanum tuberosum 91-98
