<p> This subunit of the FadBA complex has acetyl-CoA C-acyltransferase (<db_xref db="EC" dbkey="2.3.1.16"/>) activity, and is also known as beta-ketothiolase and fatty oxidation complex, beta subunit. This protein is almost always located adjacent to FadB (<db_xref db="INTERPRO" dbkey="IPR012799"/>). The FadBA complex is the major complex active for beta-oxidation of fatty acids in <taxon tax_id="562">Escherichia coli</taxon>.</p>
