Abstract
The present invention relates to an enzyme process for the one-step conversion of cephalosporin C or a derivative thereof into 7-aminocephalosporanic acid or a corresponding derivative thereof. The one step conversion is effected using a cephalosphorin C amidohydrolase derived from Pseudomonas Vesicularis B965, or from any cephalosporin C amidolydrolase producing or potentially producing descendants thereof, or from expression of DNA derived from Pseudomonas Vesicularis B965 or any cephalosporin C amidohydrolase producing or potentially producing descendants thereof
