FunFam 188: Anaerobic nitric oxide reductase transcription reg...

Please note: GO 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.

There are 6 GO terms relating to "molecular function"

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.
GO Term Annotations Evidence
Bacterial-type RNA polymerase enhancer sequence-specific DNA binding GO:0001150
Interacting selectively and non-covalently with a sequence of DNA that is an enhancer region that helps activate transcription of a gene or operon by a bacterial-type RNA polymerase. Enhancers for sigma-54 holoenzymes are typically located 80 to 150 base pairs upstream from the transcription start site, although they can be further away or may be downstream of the promoter. Some transcription units dependent on sigma-70 holoenzymes may also include enhancer sequences.

DNA-binding transcription factor activity GO:0003700
A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within the regulatory region of a gene to modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons.
