Fig. 6

Function analysis of promoters and 5′-UTR of xyl-doc. a Various transcriptional fusions corresponding to different xyl-doc cluster upstream subregions were constructed by fusing promoter fragments to upstream of fbfp gene, and Pthl promoter is as the control. b Activities of various fragments promoting expression of FbFP were measured fluorometrically in C. papyrosolvens grown on cellobiose. c Promoter activity of P4 and P4-UTR were compared in E. coli grown on LB medium supplemented with glucose or xylose. d Comparison of activities of Pxyl, Pxyl-UTR, and Pthl in C. papyrosolvens grown on different carbon sources. Error bars indicate s.d. of mean of experiments in triplicate (*P < 0.05, **P < 0.01; Student’s t test)
