mapping of the 16-kilobase-pair pseudomonas dna segment with restriction enzymes and subcloning of additional portions , one of which contained the gene for formiminoglutamate hydrolase and another that could constitutively express activities for both imidazolone propionate hydrolase and formylglutamate hydrolase , has provided evidence for the organization of all hut genes .
