Biochemical and mass spectrometric analysis of the Klebsiella aerogenes urease accessory proteins (555.10)
Urease, which hydrolyzes urea into carbonic acid and ammonia, requires nickel, GTP, bicarbonate, and several accessory proteins for its activation through metallation. This work focuses on the soluble accessory protein complex containing a maltose binding protein/UreD fusion (MBP‐UreD), UreF, and Ur...
