6.3.2.26	additional information	exchange of the conserved motifs 3371EGHGRE3376 (located in the putative epimerase domain) and 3629GWSFG3633 (located in the thioesterase domain) by site-directed-mutagenesis to LGFGLL and GWAFG, respectively, combined with deletion of the whole thioesterase domain (230 amino acids) and the different parts of this domain. The mutant enzymes show lower or null activity compared to the control strain	-, 727108
