Regulation summary diagram for nudE

Subunit composition of ADP-sugar pyrophosphorylase = [NudE]2
         ADP-sugar pyrophosphorylase = NudE

NudE belongs to the family of Nudix hydrolases [Bessman96]. The enzyme is specific for nucleoside pyrophosphates with an ADP moiety; preferred substrates of NudE include adenosine(5')triphospho(5')adenosine (Ap3A), ADP-ribose, and NADH [OHandley98].

Gel filtration experiments suggest that the enzyme is a dimer in solution [OHandley98]. A crystal structure has been solved at 2.32 Å resolution [Badger05].

An mrcA nudE yrfF triple mutant exhibits phenotypes including mucoidy, heat sensitivity, growth defects, and resistance to phage or antibiotic drugs, whereas a single mrcA mutant does not [Meberg01].

Expression of nudE may be regulated by ArcA [Federowicz14].
