2.3.1.179 C163Q site-directed mutagenesis, interaction with platensimycin compared to the interaction with the wild-type enzyme 676148 2.3.1.179 C164A site-directed mutagenesis, inactive mutant 674581 2.3.1.179 C164A/H337A site-directed mutagenesis, inactive mutant 674581 2.3.1.179 C164A/K332A site-directed mutagenesis, inactive mutant 674581 2.3.1.179 C164Q site-directed mutagenesis, a mutant in which the binding site is altered to resemble the substrate-bound state 735397 2.3.1.179 E122K the mutant is less inhibited by cerulenin and platensimycin compared to the wild type enzyme and is resistant towards inhibition by acylated sulfonamides -, 755804 2.3.1.179 E346A site-directed mutagenesis, the mutant shows similar activity compared to the wild-type enzyme 674581 2.3.1.179 E383A crystal structure determination and comparison to the wild-type enzyme, the mutation E383A appears to play a key role in disfavouring the less desirable triclinic crystal form and in generating a new surface for a packing interaction that stabilizes the new crystal form 701462 2.3.1.179 E396A site-directed mutagenesis, the mutant shows no condensation activity but retains about 50% of wild-type transacylation activity with acyl-ACP and ACP, and 40% of wild-type decarboxylation activity 674581 2.3.1.179 F107I less efficient than wild type protein 719275
