| Short Name | N2O_reductase_NosL |
| description | NosL is one of the accessory proteins of the nos (nitrous oxide reductase) gene cluster. NosL is a monomeric protein of 18,540 MW that specifically and stoichiometrically binds Cu(I). The copper ion in NosL is ligated by a Cys residue, and one Met and one His are thought to serve as the other ligands. It is possible that NosL is a copper chaperone involved in metallocentre assembly [].This entry also contains HTH-type transcriptional repressors, including YcnK. YcnK may act as a negative transcriptional regulator of YcnJ inthe presence of copper and may use copper as a corepressor. The gene, ycnK, is significantly induced under copper-limiting conditions []. |
