The Nudix hydrolase superfamily

Nudix hydrolases are found in all classes of organism and hydrolyse a wide range of organic pyrophosphates, including nucleoside di- and triphosphates, dinucleoside and diphosphoinositol polyphosphates, nucleotide sugars and RNA caps, with varying degrees of substrate specificity. Some superfamily members, such as Escherichia coli MutT, have the ability to degrade potentially mutagenic, oxidised nucleotides while others control the levels of...
