Fig. 3. CYP gene screening and functional identification of CYP728B70.
a Hierarchical clustering of RNA-Seq expression data after filtering by expression level. b Relative expression of 10 candidate CYPs and triptolide concentration in RNAi suspension cells. c Co-expression of CYP728B70 and TwCPR3 in miltiradiene engineering yeast. d In vivo transformation of authentic diterpene alcohol substrates to the corresponding alcohols and acids in cultures of yeast cells expressing CYP728B70. e In vivo transformation of authentic diterpene substrates to the corresponding alcohols and acids in cultures of yeast cells expressing CYP728B70. f Relative expression of CYP728B70, as well as triptolide concentration in CYP728B70-overexpressing suspension cells on the 3rd, 5th, 7th, 9th day. Error bars, mean ± SD (n = 3 biologically independent samples; *P < 0.05, **P < 0.01 by 2-sided Student’s t test). Source data underlying Figs. 3a, b, f are provided as a Source Data file.
