Abstract

Nucleobase and vitamin C transport Nucleobase/ascorbate transporter (NAT) proteins are responsible for the uptake of nucleotide bases by many organisms and for the transport of vitamin C in mammals. Here Lu et al. present the first X-ray crystal structure of an NAT protein, the uracil:H+ symporter UraA from Escherichia coli. The protein consists of a core domain and a gate domain, and uracil is found at the interface between the two domains. Structural and biochemical analyses suggest how uracil transport occurs and how it is coupled to the transport of a proton.
