Effect of the Fd-15aa-HydA fusion on the hydrogen production rates in PSI reactions under noncompetitive and competitive reaction conditions

Fd concentration, μM	Noncompetitive hydrogen production rate^*		Competitive hydrogen production rate with NADP⁺ and FNR^*
	HydA	Fd-15aa-HydA	HydA	Fd-15aa-HydA
0	1	10	1	8
10	25	45	5	35

Noncompetitive, PSI (10 μg), HydA (0.1 μM) or Fd-15aa-HydA, (1 μM), PC (8 μM).

Competitive, same with addition of NADP⁺ (2.5 mM) FNR (0.1 μM).

^*Rates are in units of μmol H₂ mg Chl^-1 h^-1.
