description
[Pubmed|12354229]
regulation
expression during spore [wiki|germination] is strongly reduced under conditions of osmotic stress [Pubmed|27766092]
induced by iron starvation (second wave to allow iron scavenging from the environment) ([protein|F899F1EE27E6D503BCC06BC52E3C7FD80B8EF725|fur]) [pubmed|29133393]
regulatory mechanism
[protein|F899F1EE27E6D503BCC06BC52E3C7FD80B8EF725|fur]: repression, [pubmed|12354229], in [regulon|protein:F899F1EE27E6D503BCC06BC52E3C7FD80B8EF725|fur regulon]
[protein|EB28A65CECE994DF2DF486DEACF40F2533703DB0|btr]: activation, in the presence of the co-activators bacillibactin or enterobactin [Pubmed|17725565], in [regulon|protein:EB28A65CECE994DF2DF486DEACF40F2533703DB0|btr regulon]

additional information
the presence of an iron-responsive element bound by [wiki|CitB] between ''[wiki|feuA]'' and ''[wiki|feuB]'' suggests iron-dependent regulation by [wiki|CitB] [Pubmed|10468622]
