ABSTRACT:
A novel method for the production of (S)3-hydroxy-3-methylglutaryl coenzyme A provided for the enzymatic conversion of 3-methylcrotonyl coenzyme A to the desired product. The enzyme is obtained from Pseudomonas citronellolis by ammonium sulfate precipitation of a cellular lysate. The precipitate is then redissolved in a suitable buffer and yields of over 60% have been obtained by direct reaction in the buffer.
