<p>This entry represents a structural domain with an alpha/beta sandwich topology with anti-parallel beta-sheets: (beta/alpha/beta)2. This domain is believed to be the ACP (acyl carrier protein) binding region of the malonyl-CoA ACP transacylase enzyme (FabD) found in bacteria, or in the homologous domain from eukaryotic fatty acid synthase [<cite idref="PUB00029120"/>]. </p>
