DESCRIPTION

Also known as ATOS_ECOLI, atoS. Member of the two-component regulatory system AtoS/AtoC. In the presence of acetoacetate, AtoS/AtoC stimulates the expression of the atoDAEB operon, leading to short chain fatty acid catabolism and activation of the poly-(R)-3-hydroxybutyrate (cPHB) biosynthetic pathway. Also induces the operon in response to spermidine (PubMed:16153782, PubMed:16564134, PubMed:17475408). Involved in the regulation of motility and chemotaxis, via transcriptional induction of the flagellar regulon (PubMed:22083893). AtoS is a membrane-associated kinase that phosphorylates and activates AtoC in response to environmental signals (PubMed:16153782, PubMed:18534200). Homodimer.
