Abstract:
1. A method for increasing the capacity of a green alga to produce hydrogen, comprising transforming said alga with a polynucleotide encoding a type II NAD(P)H dehydrogenase (NDH-II), wherein said NDH-II: (a) has at least one copy of the consensus motif GxGxxG in its sequence, where “G” represents a glycine and “x” represents any amino acid, and (b) has the ability to catalyze the reduction of quinones of electron transport chains through the oxidation of NADH or NADP, using a flavin cofactor, and (c) acts as a monomer of 30 to 60 kDa or as a homodimer; and wherein said transformation results in expression of said NDH-II in said alga.
