FIG. 4.

Growth of deletion mutants of the small hydrogenase subunit (ΔehbM) and the large hydrogenase subunit (ΔehbN) in rich (McCA, closed symbols) and minimal (McA, open symbols) media. (A) Growth of the ΔehbM strain S960 (squares), strain S963 containing the ΔehbM mutation complemented with pMEV2+ehbM (triangles), and the parental strain S900 (circles). (B) Growth of the ΔehbN strain S965 (squares), strain S968 containing the ΔehbN mutation complemented with pMEV2+ehbN (triangles), and the parental strain S900 (circles). For other experimental conditions, see the legend to Fig. 3.
