[[Image:svs.jpg|300px|left|thumb|]]'''Simvastatin synthase''' (LovD) is a 46 kDa acyltransferase found in the lovastatin biosynthetic pathway and catalyzes the final step of [[Lovastatin]] biosynthesis<ref name="paper4">PMID:17113998</ref>. Pictured here is the generated double mutant C40A/C60N (G0), from wild type LovD (Figure 1).This enzyme is isolated from the natural product biosynthetic pathways of [http://en.wikipedia.org/wiki/Aspergillus_terreus ''Aspergillus terreus''], specifically the polyketide biosynthetic pathway. Simvastatin Synthase converts the inactive monacolin J acid (MJA) by dimethylbutyryl chloride to yield the protected form of simvastatin (Figure 2), which subsequently undergoes lactonization to yield [[Simvastatin]]<ref name="paper5">PMID:19875080</ref>. | [[Image:svs.jpg|300px|left|thumb|]]'''Simvastatin synthase''' (LovD) is a 46 kDa acyltransferase found in the lovastatin biosynthetic pathway and catalyzes the final step of [[Lovastatin]] biosynthesis<ref name="paper4">PMID:17113998</ref>.
