[protein|search|SigA] [Pubmed|25031425]Regulation
induction by lactate [Pubmed|19201793]repressed by [protein|search|SinR] [Pubmed|19201793]part of the iron sparing response, down-regulation in a'' [protein|search|fur]'' mutant ([protein|search|Fur], [protein|search|FsrA], [protein|search|FpbB]) [Pubmed|22427629]Regulatory mechanism
dual repression by [protein|search|LutR] (inducer lactate) and [protein|search|SinR] [Pubmed|19201793][protein|search|SinR]: transcription repression [Pubmed|19201793][protein|search|FsrA]: translational repression [Pubmed|22427629][protein|search|FbpB]: acts as RNA chaperone, increases interaction between ''[protein|search|fsrA]'' and ''[protein|search|lutA]-[protein|search|lutB]-[protein|search|lutC]'' RNAs [Pubmed|22427629]Biological materials
