In enzymology, a diferric-transferrin reductase (EC 1.16.1.2) is an enzyme that catalyzes the chemical reaction
- transferrin[Fe(II)]2 + NAD+ + H+ transferrin[Fe(III)]2 + NADH
The 3 substrates of this enzyme are [[transferrin[Fe(II)]2]], NAD+, and H+, whereas its two products are [[transferrin[Fe(III)]2]] and NADH.
This enzyme belongs to the family of oxidoreductases, specifically those oxidizing metal ion with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is transferrin[Fe(II)]2:NAD+ oxidoreductase. Other names in common use include diferric transferrin reductase, NADH diferric transferrin reductase, and transferrin reductase. This enzyme participates in porphyrin and chlorophyll metabolism.
Structural studies
[edit]As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1L5T.
