EXPRESSION
ORGANISM
UNIPROT
LITERATURE
a 2.2fold induction of expression is observed in the presence of the superoxide-generating agents methyl viologen and 2,3-dimethoxy-1,4-naphthoquinone
enzyme expression is highly induced in response to treatments with paraquat or sodium hypochlorite
-
free enzyme activity increases under iron deficiency and during diazotrophic conditions
low CO2 enhances the expression and activity of FNR and the cyclic photosystem I mediated by FNR
-
the level of Fpr is significantly increased in Escherichia coli cultured in lower iron concentrations (0.017-12.2 ppm)
the petH gene encoding ferredoxin:NADP+ oxidoreductase has two translation products depending on growth conditions and leading to two isoforms. Under standard conditions where FNRL accumulates, two transcriptional start points are found at -52 and -34 relative to the first translation start site. Under nitrogen-starvation conditions where FNRS accumulates a transcriptional start point is mapped at -126 relative to the first translation start site. Therefore, the transcript responsible for FNRS translation is longer than that producing FNRL
transcriptional regulator NtcA binding to this distal promoter is responsible for the enzyme'S translation in heterocysts
