3.6.1.13 Co2+ absolute requirement for divalent metal ion is satisfied by Mn2+, Co2+ or Mg2+ 209861 3.6.1.13 Co2+ marginally effective in activation 667823 3.6.1.13 Mg2+ - 209867, 684834, 690090 3.6.1.13 Mg2+ 1 mM required for optimal activity 655991 3.6.1.13 Mg2+ 5 mM required for optimal activity 655991 3.6.1.13 Mg2+ absolute requirement for divalent metal ion is satisfied by Mn2+, Co2+ or Mg2+ 209861 3.6.1.13 Mg2+ absolutely required, activates at 5 mM 690189 3.6.1.13 Mg2+ activates 209859, 654833 3.6.1.13 Mg2+ ADPRibase-I is highly specific for ADPribose and IDPribose in presence of Mg2+, but active also on non-reducing ADP-hexoses and dinucleotides when Mg2+ is replaced with Mn2+. ADPRibase-Mn is a Mn2+-dependent diphosphatase active on ADPribose and IDPribose, dinucleotides and CDP alcohols. ADPribase-II is a rather unspecific diphosphatase that, with Mg2+, is active on AMP or IMP containing NDP sugars and dinucleotides, and with Mn2+ also active on non-adenine NDP-sugars and CDP-alcohols 209868 3.6.1.13 Mg2+ binding structure, overview 687404
