Organism
Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
Lineage
Bacteria; Pseudomonadati; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK4233
Summary
Activated NrdD is predicted to be cleaved by oxygen at the Gly681 radical, dropping the last 31 aa. [More information is available at EcoGene: EG11417]. The NrdD reductase is activated by the NrdG activase under anaerobic conditions and is inactivated by oxygen. [More information is available at EcoCyc: EG11417].
