Iron:rusticyanin reductase (EC 1.16.9.1, Cyc2) is an enzyme with systematic name Fe(II):rusticyanin oxidoreductase.^{[1][2][3][4][5][6][7]} This enzyme catalyses the following chemical reaction

Fe(II) + rusticyanin $\rightleftharpoons$ Fe(III) + reduced rusticyanin

Rusticyanin reductase contains c-type heme.
