Nitrate reductase

Homodimers, two identical subunits

Each subunit with 100kD

Each subunit contains 3 prosthetic groups:

FAD, heme, and molybdenum complexed to pterin (an organic molecule).

The signals flow from the chloroplast to the nucleus is retrograde:

plastidial ferrochelatase I catalyzes the synthesis of heme, which in turn regulates the expression of nuclear encoded, chloroplast‐targeted proteins in greening leaves.
