(a) S. rapammycinicus ATCC29253. (b) Streptomyces iranensis. (c) Actinoplanes sp. N902-109. 6 FIG S2 Construction and verification of overexpression mutants. (a) Expression plasmids were constructed in pSET152 derivative containing an ermE* promoter with PacI and XbaI (insert: rapY or rapS or rapR or rapX). For southern hybridization, ermE* promoter was used as a probe and the genomic DNAs were digested by KpnI and XbaI. (b) Overexpression of rapY, rapR and rapS in S. rapamycinicus, respectively, lane 1, DIG labled marker; lane 2, rapR overexpression mutants; lane 3, rapY overexpression mutants; lane 4, rapS overexpression mutants. (c) Complementation of ΔrapY and ΔrapS by pRAPY and pRAPS, respectively, lane1, ΔrapY; lane 2, ΔrapS; lane 3-4, ΔrapY/pRAPY; lane 5-6, ΔrapS/pRAPS; lane 7, DIG labeled marker. (d) Overexpression of rapX in S. rapamycinicus and ΔrapS strains, lane 1, wild-type strain as a control; lane 2, ΔrapS; lane 3, WT/pRAPX; lane 4, ΔrapS/pRAPX; lane 4, DIG labeled marker. 7 FIG S3 Construction and verification of rapY in-frame deletion in S. rapamycinicus. (a) Schematic representation of rapY in-frame deletion by homologous recombination. (b) Southern hybridization analysis. Genomic DNA restricted with kpnI from wild-type (lane 1), single-crossover mutant (lane 10), and wild-type revertant (lane 2, 3, 4, 7, 8, 9). Genomic DNA restricted with KpnI and XbaI from double-crossover ΔrapY mutant (lane 6). Molecular weight marker (lane 5). The HindIII-XbaI fragment of LA was used as a probe. 8 FIG S4 Construction and verification of rapS in-frame deletion in S. rapamycinicus. (a) Schematic representation of rapS in-frame deletion by homologous recombination. (b) Southern hybridization analysis. Genomic DNA restricted with PvuII and NotI from wild-type (lane 8), single-crossover mutant (lane 9), double-crossover ΔrapS mutant (lane 1), and wildtype revertant (lane 2, 3, 6, 7) strains. Lane 4 was not detected. DIG labeled marker (lane 5). The XbaI-EcoRI fragment of RA was used as a probe. 9
