WebLegend. Settings. Analysis WebMar 2, 2013 · A mechanism for FkbO is proposed based on both interactions between the inhibitor and the surrounding amino acids and an FkbO structure with chorismate modelled in the active site. We suggest that the methylene group of the chorismate enol ether takes up a proton from an active-site glutamic acid residue, thereby initiating chorismate …
WebTacrolimus biosynthetic machinery should incorporate the shikimate-derived 4,5-dihydroxycyclohex-1-enecarboxylic acid (DHCHC) as a biosynthetic starter unit into the biosynthetic line of tacrolimus. fkbO is a homologue of rapK encoding chorismatase related to the biosynthesis of starter unit DHCHC from chorismate in the rapamycin biosynthetic ... WebWe now provide evidence that FkbO and RapK are actually chorismate hydrolases, yielding DCDC (Fig. 2). We have also found that other previously obscure FkbO- and …
