Fig. 2From: Improving the production of 9α-hydroxy-4-androstene-3,17-dione from phytosterols by 3-ketosteroid-Δ1-dehydrogenase deletions and multiple genetic modifications in Mycobacterium fortuitumPhylogenetic analysis of the putative 3-Ketosteroid-Δ1-dehydrogenases (KstDs) in Mycobacterium fortuitum ATCC 35855 and some representative orthologues. KstDs in M. fortuitum ATCC 35855 is marked in red. Different colors refer to different evolutionary branches. The scale length is set at 0.2Back to article page
