1 Lysine 129 of CD38 (ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase) participates in the binding of ATP to inhibit the cyclic ADP-ribose hydrolase. Lysine CD38 molecule Homo sapiens
2 Sequence analysis of the lysylendopeptidase-digested fragment of the labeled CD38 indicated that the FSBA-labeled residue was Lys-129. Lysine CD38 molecule Homo sapiens
3 We introduced site-directed mutations to change the Lys-129 of CD38 to Ala and to Arg. Lysine CD38 molecule Homo sapiens
4 These results indicate that Lys-129 of CD38 participates in cADPR binding and that ATP competes with cADPR for the binding site, resulting in the inhibition of the cADPR hydrolase activity of CD38. Lysine CD38 molecule Homo sapiens
5 These results indicate that Lys-129 of CD38 participates in cADPR binding and that ATP competes with cADPR for the binding site, resulting in the inhibition of the cADPR hydrolase activity of CD38. Lysine CD38 molecule Homo sapiens
