Screening of bottleneck reaction steps in the 1w–SmHBA operon by multienzyme catalysis. a, Schematic illustration of the reaction components. The in vitro reaction system consisted of crude cell extracts (CCE) from strains harboring the 1w–SmHBA plasmid as the basic catalytic source, supplemented with multienzyme-expressing strains carrying plasmids encoding 4–5, 2–3, or single heterologously expressed Cob enzymes to alter the enzyme composition in each reaction. b, Comparison of in vitro HBA production using CCE from strains H1, H2, and LvH0.

Screening of bottleneck reaction steps in the 1w–SmHBA operon by multienzyme catalysis. a, Schematic illustration of the reaction components. The in vitro reaction system consisted of crude cell extracts (CCE) from strains harboring the 1w–SmHBA plasmid as the basic catalytic source, supplemented with multienzyme-expressing strains carrying plasmids encoding 4–5, 2–3, or single heterologously expressed Cob enzymes to alter the enzyme composition in each reaction. b, Comparison of in vitro HBA production using CCE from strains H1, H2, and LvH0. Two-sided unpaired t -test is carried out between H1, H2, and LvH0. Unpaired t -test of data: H1 to H2, ∗∗∗∗, P < 0.0001 (t = 35.12); LvH0 to H2, ∗∗∗∗, P < 0.0001 (t = 30.84). c, In vitro HBA production using CCE from H21–H28 strains, each harboring an additional RcCob enzyme. Red bars indicate values higher than those of the H2 reactant, whereas blue bars indicate values lower than those of H2 reactant. Two-sided unpaired t -test is carried out between H1 to H21-28.
