KS-AT1

KS Part

Headline text

The leading role of the KS part is Ketocaylsynthase, KS domain. Its last step is activation of propionyl groups. AT domains in Module 1 or Module 2 activate the propionyl groups in (2S)Methylmalonyl-CoA (details in Loading Part). Afterwards, KS domains combine the extended units anchored on the ACP domains belonging to the Modules which the KS domains belong to with the polyketide chains anchored on the ACP domains belonging to the former Modules (or Loadings). Then new polyketide chains form and are anchored the ACP domains belonging to the Modules which the KS domains belong to.

The function of KS domain is combining the propionyl group with acetyl group at the end of the polyketide chain by forming the C—C bond. In KS domain catalyzed reactions, polyketide chains are transferred from ACP domains belonging to the former Module (or Loading) onto KS domains, and then occur decarboxylic reaction with the extended units anchored on the ACP domains belonging to the Modules which the KS domains belong to. As a result, the polyketide chains are elongated.
