oleD glucosyltransferase; S. antibiotics (characterized)
This oleandomycin glucosyltransferase was found to glucosylate indoxyl to produce indoxyl-B-glucoside, or indican. To the best of our knoweldge, this is the first recombinant enzyme used to produce indican. Kaempferol is another substrate of this enzyme. It is known to highly promiscuous in substrate specificity and glucosylates a variety of phenolics and anthrocyanins. The sequence shown here corresponds to that of UniProt ID Q3HTL6, and encodes the ORF only. This is the characterized and slightly altered version of BBa_K1131004. The last 15 amino acids have been removed from this version increasing its solubility greatly. A mutated version known to have even broader activity was added to the Registry as well.

Absorbance data obtained from HPLC at 270nm. Reaction containing Kaempferol, OleD, and donor molecule UDP-glucose. Peaks for kaempferol and kaempferol glucoside are observed demonstrating the successful purification of active OleD.
Absorbance data obtained from HPLC at 270nm. Reaction containing indoxyl, OleD, and donor molecule UDP-glucose peaks for indican and sodium complexed indican are observed along with the precursor indoxyl.
Mass spectrometry data for the elution fraction at a retention time of 9.51 (Indican peak in HPLC data shown in previous figure). Peaks matching the mass of the precursor indoxyl (134), indican (296), and sodium complexed indican (318) were found. All unlabeled peaks did not correspond to expected ions.
