title: Sequencing and heterologous expression of the gene encoding penicillin V amidase from Bacillus sphaericus.
abstract: The Bacillus sphaericus gene encoding penicillin V amidase, which catalyzes the hydrolysis of penicillin V, has been characterized. The entire nucleotide sequence of the coding region, as well as 5'- and 3'-flanking regions, was determined using an improved sequencing strategy. The deduced amino acid sequence suggests a protein consisting of 338 residues with an Mr of 37,500. The ATG initiator codon is preceded by a putative ribosome-binding site, typical for genes of Gram-positive origin. High expression of the gene was obtained in Escherichia coli using an inducible promoter, showing that the gene product is stable in this heterologous host.
