FunFam 36179: Sulfite reductase (NADPH) hemoprotein beta-compone...

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Assimilatory sulfite reductase (NADPH). [EC: 1.8.1.2]
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.
