Nucleoside Triphosphate Pyrophosphohydrolase (EC 3.6.1.8) N-terminal tandem-domain of MazG ...
 6-119 2.25e-59

Nucleoside Triphosphate Pyrophosphohydrolase (EC 3.6.1.8) N-terminal tandem-domain of MazG proteins from Escherichia coli and bacterial homologs; MazG is a NTP-PPase that hydrolyzes all canonical NTPs into their corresponding nucleoside monophosphates and pyrophosphate. The prototype of this family is MazG proteins from Escherichia coli (EcMazG) that represents the most abundant form consisting two sequence-related domains in tandem, this family corresponding to the N-terminal MazG-like domain. EcMazG functions as a regulator of cellular response to starvation by lowering the cellular concentration of guanosine 3',5'-bispyrophosphate (ppGpp). EcMazG exists as a dimer; each monomer contains two tandem MazG-like domains with similarly folded globular structures. However, only the C-terminal domain has well-ordered active site and exhibits an NTPase activity responsible for the regulation of bacterial cell survival under nutritional stress. Divalent ions, such as Mg2+ or Mn2+, are required for activity; however, this domain does not exhibit an NTPase activity despite containing structural features such as the EEXX(E/D) motif and key basic catalytic residues responsible for nucleotide pyrophosphohydrolysis activity. It is suggested that the N-terminal domain of EcMazG might have a house-cleaning function by hydrolyzing noncanonical NTPs whose incorporation into the nascent DNA leads to increased mutagenesis and DNA damage.

 27-100 4.70e-31

MazG nucleotide pyrophosphohydrolase domain; This domain is about 100 amino acid residues in length. It is found in the MazG protein from E. coli. It contains four conserved negatively charged residues that probably form an active site or metal binding site. This domain is found in isolation in some proteins as well as associated with pfam00590. This domain is clearly related to pfam01503 another pyrophosphohydrolase involved in histidine biosynthesis. This family may be structurally related to the NUDIX domain pfam00293 (Bateman A pers. obs.).

 6-119 2.25e-59

Nucleoside Triphosphate Pyrophosphohydrolase (EC 3.6.1.8) N-terminal tandem-domain of MazG proteins from Escherichia coli and bacterial homologs; MazG is a NTP-PPase that hydrolyzes all canonical NTPs into their corresponding nucleoside monophosphates and pyrophosphate. The prototype of this family is MazG proteins from Escherichia coli (EcMazG) that represents the most abundant form consisting two sequence-related domains in tandem, this family corresponding to the N-terminal MazG-like domain. EcMazG functions as a regulator of cellular response to starvation by lowering the cellular concentration of guanosine 3',5'-bispyrophosphate (ppGpp). EcMazG exists as a dimer; each monomer contains two tandem MazG-like domains with similarly folded globular structures. However, only the C-terminal domain has well-ordered active site and exhibits an NTPase activity responsible for the regulation of bacterial cell survival under nutritional stress. Divalent ions, such as Mg2+ or Mn2+, are required for activity; however, this domain does not exhibit an NTPase activity despite containing structural features such as the EEXX(E/D) motif and key basic catalytic residues responsible for nucleotide pyrophosphohydrolysis activity. It is suggested that the N-terminal domain of EcMazG might have a house-cleaning function by hydrolyzing noncanonical NTPs whose incorporation into the nascent DNA leads to increased mutagenesis and DNA damage.

This domain is found in isolation in some proteins as well as associated with pfam00590. This domain is clearly related to pfam01503 another pyrophosphohydrolase involved in histidine biosynthesis.

 22-73 7.79e-05

Nucleoside Triphosphate Pyrophosphohydrolase (EC 3.6.1.8) MazG-like domain superfamily; This superfamily contains enzymes that hydrolyze the alpha-beta phosphodiester bond of all canonical NTPs into monophosphate derivatives and pyrophosphate (PPi). Divalent ions, such as Mg2+ ion(s), are essential to activate a proposed water nucleophile and stabilize the charged intermediates to facilitate catalysis. These enzymes share a conserved divalent ion-binding motif EXX[E/D] in their active sites. They also share a highly conserved four-helix bundle, where one face forms the active site, while the other participates in oligomer assembly. The four-helix bundle consists of two central antiparallel alpha-helices that can be contained within a single protomer or form upon dimerization. The superfamily members include dimeric dUTP pyrophosphatases (dUTPases; EC 3.6.1.23), the nonspecific NTP-PPase MazG proteins, HisE-encoded phosphoribosyl ATP pyrophosphohydolase (PRA-PH), fungal histidine biosynthesis trifunctional proteins, and several uncharacterized protein families.

However, unlike typical tandem-domain MazG proteins, BsYpjD contains a single MazG-like domain.
