Fig. 5From: Roles of the crotonyl-CoA carboxylase/reductase homologues in acetate assimilation and biosynthesis of immunosuppressant FK506 in Streptomyces tsukubaensis Growth of various mutants of S. tsukubaensis on the minimal medium (a) in which the acetate is present as a sole carbon source and on complex medium ISP4 (b). Strains WT (S. tsukubaensis NRRL 18488); 1 Δemc (b); 2 Δemc + emc (d); 3 Δemc + allR_ecmOp (e); 4 Δemc + allR_ecmOp + ccr1 (e1); 5 Δemc + ccr1 (c). Letters in brackets correspond to the labels of the constructs presented on Fig. 4 Back to article page
