Tacrolimus (FK506), derived from various soil Streptomyces species, is a potent macrolide immunosuppressant that is assembled by a typical polyketide synthase (PKS)-nonribosomal peptide synthetase (NRPS) hybrid system.Its chemical structure is unique, with a piperidine unit consisting in the polyketide skeleton, a 4-methoxy, 5-hydroxy-cyclohexyl functional group, as well as methoxyl and allyl side chains.Recently, studies on the biosynthetic mechanism of tacrolimus, particularly for the pathways encoding the unusual precursors, achieved great successes.In this review, we summarize the enzymatic basis in correspondence to the biosynthesis of tacrolimus, and emphasize on the recent progress in understanding the biosynthetic pathways of the unusual precursors 4,5-dihydroxycyclohex-1-enecarboxylic acid (DHCHC), methoxymalonyl-acyl carrier protein (ACP), allylmalonyl-coenzyme A (CoA) and L-pipecolic acid.
