Enzyme Information
| 1.8.1.2 |
Assimilatory sulfite reductase (NADPH).
based on mapping to UniProt P38038
H(2)S + 3 NADP(+) + 3 H(2)O = sulfite + 3 NADPH.
-!- The enzyme, which catalyzes the six-electron reduction of sulfite to sulfide, is involved in sulfate assimilation in bacteria and yeast. -!- Different from EC 1.8.99.5, which is involved in prokaryotic sulfur- based energy metabolism. -!- Formerly EC 1.8.99.1.
