Highly reducing polyketide synthase
Webagents.1,2 The biosynthesis of polyketide in fungi is performed by Type I iterative polyketide synthases (IPKSs), which are multidomain megasynthases.3 The highly reducing IPKSs (HRPKSs) are a large subgroup of the IPKSs that are associated with the biosynthesis of highly reduced compounds, such as lovastatin and fumonisin. The minimal PKS ...
