The invention relates to a cephalosporin acetylhydrolase gene, a recombinant DNA molecule prepared by introducing the gene into a vector used in an E. coli host-vector system, E. coli cells transformed with the recombinant DNA molecule, a protein having the amino acid sequence encoded by the gene, an enzyme which is a multimer of the protein, and a process for preparing the protein or enzyme. The cephalosporin acetylhydrolase is an enzyme useful for converting cephalosporins, e.g. cephalosporin C and 7-ACA, into deacetylated ones, e.g. deacetylcephalosporin C and deacetyl 7-ACA, which are useful as intermediates in the preparation of a variety of derivatized cephalosporin antibiotics.
