FunFam 11397: Cytochrome c oxidase, cbb3-type

There are 3 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
Cytochrome-c oxidase. [EC: 1.9.3.1]
4 ferrocytochrome c + O(2) + 4 H(+) = 4 ferricytochrome c + 2 H(2)O.
  • The reduction of O(2) to water is accompanied by the extrusion of four protons from the intramitochondrial compartment.
  • Several bacteria appear to contain analogous oxidases.

Ribonuclease E. [EC: 3.1.26.12]
Endonucleolytic cleavage of single-stranded RNA in A- and U-rich regions.
  • RNase E is a bacterial ribonuclease that plays a role in the processing of ribosomal RNA (9S to 5S rRNA), the chemical degradation of bulk cellular RNA, the decay of specific regulatory, messenger and structural RNAs and the control of plasmid DNA replication.
  • The enzyme binds to monophosphorylated 5' ends of substrates but exhibits sequential cleavages in the 3' to 5' direction.
  • 2'-O-methyl nucleotide substitutions at RNase E binding sites do not prevent binding but do prevent cleavage of non-modified target sequences 5' to that locus.
  • In Escherichia coli, the enzyme is found in the RNA degradosome.
  • The C-terminal half of the protein contains binding sites for the three other major degradosomal components, the DEAD-box RNA helicase Rh1B, EC 4.1.1.11 and EC 2.7.7.8.
  • Formerly EC 3.1.26.n1.

Nitric-oxide reductase (cytochrome c). [EC: 1.7.2.5]
Nitrous oxide + 2 ferricytochrome c + H(2)O = 2 nitric oxide + 2 ferrocytochrome c + 2 H(+).
  • The enzyme from Pseudomonas aeruginosa contains a dinuclear center comprising a non-heme iron center and heme b3, plus heme c, heme b and calcium; the acceptor is cytochrome c551.
  • Formerly EC 1.7.99.7.
