Cloning and sequencing of a corn (Zea mays) nuclear gene coding for the chloroplast specific catalytic subunit of ferredoxin-thioredoxin reductase.

We determined the complete nucleotide sequence of a cDNA clone encoding the smaller, catalytic subunit of ferredoxin-thioredoxin reductase from corn chloroplasts. The translated protein sequence, representing a subunit of 12.9 kDa shows 80% identity with the protein sequence from spinach and contains seven Cys residues all at conserved positions.
