Abstract

Official abstract text for this publication.

The present disclosure provides acyltransferases useful for synthesizing therapeutically important statin compound.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of making simvastatin comprising contacting monacolin J or lovastatin substrate with an isolated recombinant variant LovD polypeptide having at least 90% sequence identity to the amino acid sequence of SEQ ID NO: 2, wherein the amino acid sequence of said LovD polypeptide comprises the substitution S172N, in the presence of an α-dimethylbutyryl thioester co-substrate and under conditions in which simvastatin is produced. 2. The method of claim 1 , wherein the monacolin J is a sodium salt. 3. The method of claim 2 , wherein the monacolin J is a sodium salt and activated charcoal is added. 4. The method of claim 1 , wherein the monacolin J is an ammonium salt. 5. The method of claim 4 , wherein an agent for precipitating simvastatin is added. 6. The method of claim 5 , wherein said agent is ammonium hydroxide. 7. The method of claim 1 , wherein said lovastatin substrate, said variant LovD polypeptide and said thioester are added at substantially the same time into a vessel. 8. The method of claim 7 , wherein said lovastatin substrate and said variant LovD polypeptide are first added into a vessel and then said thioester is added into said vessel. 9. The method of claim 1 , wherein an agent for precipitating simvastatin is added. 10. The method of claim 9 , wherein said agent is ammonium hydroxide.
