Allophanate hydrolase of Oleomonas sagaranensis involved in an ATP-dependent degradation pathway specific to urea.

abstract：:This study focused on the alanine racemase gene (alr-2), which is involved in the synthesis of d-alanine that forms the backbone of the cell wall. A stable alr-2 knockout mutant of Aeromonas hydrophila HBNUAh01 was constructed. When the mutant was supplemented with d-alanine, growth was unaffected; deprivation of d-al...
