Genetic Characterization of the Urease Gene Cluster in Photobacterium sp. Strain HA-2 Isolated from Seawater Kim, Tae Ok; Park, Kwon Sam;
In this study, we cloned and sequenced the 15,204-bp DNA region containing the gene cluster for urease production from the chromosome of the environmental Photobacterium sp. strain HA-2. We identified 15 open reading frames (ORFs) and the G+C content was 40.3%. The urease gene cluster of Photobacterium sp. strain HA-2 consisted of seven genes, namely, ureDABCEF and ureG. There were five ORFs of urease genes in the opposite direction, which were homologous to the nickel transport operons (nik) of Vibrio parahaemolyticus and Escherichia coli. The genetic organization and sequences of the urease genes of Photobacterium sp. strain HA-2 resembled those found in Vibrio fischeri and V. parahaemolyticus.
