== Function == | |||
[https://www.uniprot.org/uniprot/NDPGT_BACSU NDPGT_BACSU] Glycosyltransferase that can glycosylate a wide range of substrates, including various flavonoids, phenyl ketones, curcuminoid, lignins, zingerone, triterpenes, stilbene and anthraquinone, using UDP-glucose or ADP-glucose as sugar donor (PubMed:28315700, PubMed:33152360). It also exhibits O-, N- and S-glycosylation activities towards simple aromatics (PubMed:28315700). In vivo, the broad acceptor tolerance of YjiC might function as a detoxification agent against exogenous xenobiotics to make the strain adaptable to the changeable environment (Probable).<ref>PMID:28315700</ref> <ref>PMID:33152360</ref> <ref>PMID:28315700</ref> | |||

== Publication Abstract from PubMed == | |||
Glycosylation catalyzed by uridine diphosphate-dependent glycosyltransferases (UGT) contributes to the chemical and functional diversity of a number of natural products. Bacillus subtilis Bs-YjiC is a robust and versatile UGT that holds potentials in the biosynthesis of unnatural bioactive ginsenosides. To understand the molecular mechanism underlying the substrate promiscuity of Bs-YjiC, we solved crystal structures of Bs-YjiC and its binary complex with uridine diphosphate (UDP) at resolution of 2.18 A and 2.44 A, respectively. Bs-YjiC adopts the classical GT-B fold containing the N-terminal and C-terminal domains that accommodate the sugar acceptor and UDP-glucose, respectively. Molecular docking indicates that the spacious sugar-acceptor binding pocket of Bs-YjiC might be responsible for its broad substrate spectrum and unique glycosylation patterns toward protopanaxadiol-(PPD) and PPD-type ginsenosides. Our study reveals the structural basis for the aglycone promiscuity of Bs-YjiC and will facilitate the protein engineering of Bs-YjiC to synthesize novel bioactive glycosylated compounds. | |||
