Structural and biochemical characterization of the biuret hydrolase (BiuH) from the cyanuric acid catabolism pathway of Rhizobium leguminasorum bv. viciae 3841
Fig 2
Structure of the biuret amidohydrolase enzyme.
Cartoon representation of: A. BiuH tetrameric structure, each color represents a subunit; B. monomeric subunit of BiuH with alpha helices shown in red (numbered α1- α8), beta strands in yellow (numbered β1- β5) and loops in green. In every cases the N and/or C termini were visible, they are indicated by a black arrow. Figures 1, 3 and 6 were generated with PyMol [65].
