Nitrogen metabolism. The identified previously known and newly predicted enzyme activities of Blochmannia are compiled for the pathway of nitrogen metabolism. They involve the urease complex (Bfl523, Bfl524 and Bfl525; catalyzing the following reaction: Urea + H2O = CO2 + 2 NH3) and urease activating complex (Bfl521, Bfl522 and Bfl526) and glutamine synthetase (Bfl618). Further proteins adding to the pathway are the now confirmed ferredoxin (Bfl 480), Bfl 573 (NifU-like protein; previously conserved hypothetical) as well as beta-cystathionase (Bfl067).
