[https://www.uniprot.org/uniprot/RMLA_SALTY RMLA_SALTY] Catalyzes the formation of dTDP-glucose, from dTTP and glucose 1-phosphate, as well as its pyrophosphorolysis. Is also able to convert non natural substrates such as a wide array of alpha-D-hexopyranosyl, deoxy-alpha-D-glucopyranosyl, aminodeoxy-alpha-D-hexopyranosyl and acetamidodeoxy-alpha-D-hexopyranosyl phosphates to their corresponding dTDP- and UDP-nucleotide sugars.<ref>PMID:8382158</ref>

== Publication Abstract from PubMed ==
 +
Directed evolution is a valuable technique to improve enzyme activity in the absence of a priori structural knowledge, which can be typically enhanced via structure-guided strategies. In this study, a combination of both whole-gene error-prone polymerase chain reaction and site-saturation mutagenesis enabled the rapid identification of mutations that improved RmlA activity toward non-native substrates. These mutations have been shown to improve activities over 10-fold for several targeted substrates, including non-native pyrimidine- and purine-based NTPs as well as non-native d- and l-sugars (both alpha- and beta-isomers). This study highlights the first broadly applicable high throughput sugar-1-phosphate nucleotidyltransferase screen and the first proof of concept for the directed evolution of this enzyme class toward the identification of uniquely permissive RmlA variants.
