Abstract

Cytochrome cd1 (cyt cd1) nitrite reductase is a dimeric enzyme of the bacterial periplasm that plays a key role in denitrification, the respiratory reduction of nitrite to nitric oxide in the nitrogen cycle. Each subunit of the cyt cd1 dimer contains one cytochrome c and one d1 haem group [PubMed12556530]. The active site contains a specialised d1 haem, where the nitrite substrate is bound and reduced. This d1 haem is bound in an 8-bladed beta-propeller, which is also found in some members of the WD40 repeat-containing proteins .

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 2 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a C-terminal (heme d1) domain of cytochrome cd1-nitrite reductase domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 2 hidden Markov models representing the C-terminal (heme d1) domain of cytochrome cd1-nitrite reductase superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
