construction of the THID mutant protein, a His-tagged 61 kDA 541-amino acid region containing thioester hydrolase domain and its downstream, THID shows catalytic activity to hydrolyze a model substrate 6-methylsalicylic acid-N-acetylcysteamine. The complementation of thioester domain-deficient mutant THm by THID protein in the recombinant Escherichia coli expression system |

2.3.1.165 | more |
N-terminal deletion mutant ATXN1 lacking 44 amino acids, catalytically active. N-terminal deletion mutant ATXN2 lacking 81 amino acids including part of the ketosynthase domain, loss of catalytic activity. Both ATXC1 lacking 9 carboxyterminal amino acids and ATXC2 lacking 21 carboxyterminal amino acids including part of the conserved acyl carrier protein domain are inactive. Coexpression of inactive mutants ATXN2 with ATXC1 or ATXC2 results in restauration of activity. Identification of an interdomain region required for the formation of the active reaction center |

Saccharomyces cerevisiae strain IBT100083 with a ACC1-TEF1 promoter produces high levels of acetyl-CoA carboxylase (ACC1) which catalyzes the conversion of acetyl-CoA to malonyl-CoA. Hence, more substrate for 6-methylsalicylic acid synthase is available resulting in a higher 6-MSA production. |
