Crystal Structure Analysis of Rif16 in complex with R-LCrystal Structure Analysis of Rif16 in complex with R-L
Structural highlights
Publication Abstract from PubMedRifamycin-derived drugs, including rifampin, rifabutin, rifapentine, and rifaximin, have long been used as first-line therapies for the treatment of tuberculosis and other deadly infections. However, the late steps leading to the biosynthesis of the industrially important rifamycin SV and B remain largely unknown. Here, we characterize a network of reactions underlying the biosynthesis of rifamycin SV, S, L, O, and B. The two-subunit transketolase Rif15 and the cytochrome P450 enzyme Rif16 are found to mediate, respectively, a unique C-O bond formation in rifamycin L and an atypical P450 ester-to-ether transformation from rifamycin L to B. Both reactions showcase interesting chemistries for these two widespread and well-studied enzyme families. Deciphering the late steps of rifamycin biosynthesis.,Qi F, Lei C, Li F, Zhang X, Wang J, Zhang W, Fan Z, Li W, Tang GL, Xiao Y, Zhao G, Li S Nat Commun. 2018 Jun 14;9(1):2342. doi: 10.1038/s41467-018-04772-x.
