| F37A/L196F/C253A | site-directed mutagenesis, specific cyclic ADP-ribose phosphohydrolase obtained by mutagenic engineering of Mn2+-dependent ADP-ribose/CDP-alcohol diphosphatase. Mutagenesis of human ADPRibase-Mn at Phe37, Leu196 and Cys253 alters its specificity, the best substrate of the mutant is cyclic ADP-ribose (cADPR), the Cys253 mutation is essential for cADPR preference. The proximity to the northern ribose of cADPR in docking models indicates Cys253 is a steric constraint for cADPR positioning | Homo sapiens |
| F37A/L196F/C253G | site-directed mutagenesis, the mutant with a smaller residue 253 shows increased cADPR specificity | Homo sapiens |
| F37A/L196F/D250A/C253G | site-directed mutagenesis, the quadruple mutant shows a detrimental effect of the D250A substitution on the efficiency with all substrates (1.3-3.4fold decrease), and more markedly so for cADPR, such that the substrate efficiency ratios are less favourable than for the triple mutant F37A/L196F/C253G | Homo sapiens |
| F37A/L196F/V252A/C253G | site-directed mutagenesis, the mutant with displays the desired specificity, with cADPR kcat/KM is about 20-200fold larger than for any other substrate. The quadruple mutant shows detrimental effects of the V252A substitution on the efficiency with ADP-ribose, CDP-choline and 2',3'-cAMP (1.1-2.8fold decrease) while it increases 2fold the efficiency with cADPR | Homo sapiens |
| F37A/L196F/V252A/C253G/T279A | site-directed mutagenesis | Homo sapiens |

| evolution | ADPRibase-Mn enzymes contain the dinuclear metal centre typical of the metallo-dependent phosphatases SCOP2 superfamily, forming within it a family of their own named as ADPRibase-Mn-like. ADPRibase-Mn proteins constitute also a functional family in the CATH classification, within cluster SC:3 of superfamily 3.60.21.10 | Homo sapiens |
| physiological function | cyclic ADP-ribose (cADPR) is a messenger for Ca2+ mobilization. Its turnover is believed to occur by glycohydrolysis to ADP-ribose. ADP-ribose/CDP-alcohol diphosphatase (ADPRibase-Mn) acts as cADPR phosphohydrolase with much lower efficiency than on its major substrates | Homo sapiens |
