Biosynthesis of simvastatin
摘要
Abstract
Simvastatin was synthesized from Monacolin J using acyltransferase LovD. The objective of this study was to investigate the expression of acyltransferase LovD, and optimize its medium and fermenting conditions. The level of expression was visualized by sodium dodecyl sulfate-poryacryl-amide gel electro-phoresis. To quantify the active amount of LovD expressed under different growth conditions and in different media, an activity assay was used. The optimum fermentation conditions of acyltransferase LovD were determined as follows:fermentation medium was Terrific Broth; inoculation volume was 4% ; ceD density ( 0.0,500 ) before induction was 0. 7; concentration of IPTG was 0. 2 mmol/L; inoculation tempreture was 20 t, and total time of inoculation was 20 h. Under the conditions, the expression level of acyltransferase LovD was 100 mg/L and the yield of simvastatin was 1. 2 g/L.关键词
