Three new Nudix hydrolases from Escherichia coli.
Xu W., Dunn C.A., O'Handley S.F., Smith D.L., Bessman M.J.

Three members of the Nudix (nucleoside diphosphate X) hydrolase superfamily have been cloned from Escherichia coli MG1655 and expressed. The proteins have been purified and identified as enzymes active on nucleoside diphosphate derivatives with the following specificities. Orf141 (yfaO) is a nucleoside triphosphatase preferring pyrimidine deoxynucleoside triphosphates. Orf153 (ymfB) is a nonspecific nucleoside tri- and diphosphatase and atypically releases inorganic orthophosphate from triphosphates instead of pyrophosphate. Orf191 (yffH) is a highly active GDP-mannose pyrophosphatase. All three enzymes require a divalent cation for activity and are optimally active at alkaline pH, characteristic of the Nudix hydrolase superfamily. The question of whether or not Orf1.9 (wcaH) is a bona fide member of the Nudix hydrolase superfamily is discussed. << Less

Maf (for multicopy associated filamentation) proteins represent a large family of conserved proteins implicated in cell division arrest but whose biochemical activity remains unknown. Here, we show that the prokaryotic and eukaryotic Maf proteins exhibit nucleotide pyrophosphatase activity against 5-methyl-UTP, pseudo-UTP, 5-methyl-CTP, and 7-methyl-GTP, which represent the most abundant modified bases in all organisms, as well as against canonical nucleotides dTTP, UTP, and CTP. Overexpression of the Maf protein YhdE in E. coli cells increased intracellular levels of dTMP and UMP, confirming that dTTP and UTP are the in vivo substrates of this protein. Crystal structures and site-directed mutagenesis of Maf proteins revealed the determinants of their activity and substrate specificity. Thus, pyrophosphatase activity of Maf proteins toward canonical and modified nucleotides might provide the molecular mechanism for a dual role of these proteins in cell division arrest and house cleaning. << Less

Era is an essential GTPase in Escherichia coli, and Era has been implicated in a number of cellular functions. Homologues of Era have been identified in various bacteria and some eukaryotes. Using the era gene as bait in the yeast two-hybrid system to screen E. coli genomic libraries, we discovered that Era interacts with MazG, a protein of unknown function which is highly conserved among bacteria. The direct interaction between Era and MazG was also confirmed in vitro, being stronger in the presence of GDP than in the presence of GTPgammaS. MazG was characterized as a nucleoside triphosphate pyrophosphohydrolase which can hydrolyze all eight of the canonical ribo- and deoxynucleoside triphosphates to their respective monophosphates and PP(i), with a preference for deoxynucleotides. A mazG deletion strain of E. coli was constructed by replacing the mazG gene with a kanamycin resistance gene. Unlike mutT, a gene for another conserved nucleotide triphosphate pyrophosphohydrolase that functions as a mutator gene, the mazG deletion did not result in a mutator phenotype in E. coli. << Less
