Urea is the degradation product of a wide range of nitrogen containing biomolecules.In mammals,urea is excreted.Many plants,bacteria,algae,and fungi can use urea for their anabolism,reintegrating its nitrogen into the biosphere.The first step of their urea utilization is converting it to ammonium and carbon dioxide.One of the enzymes catalyzing such a reaction is
