From: Biochemical and structural characterization of alanine racemase from Bacillus anthracis (Ames)
Differences in hinge angle between various alanine racemases. Structural alignment of the N-terminal domain α/β barrel from B. anthracis (green), G. stearothermophilus (red), M. tuberculosis (pink), S. lavendulae (blue) and P. aeruginosa (yellow) shows that the hinge angle between N- and C-terminal domains can vary. N- and C-termini are labeled N and C and colored according to their respective structures. The PLP cofactor for Alr Bax is shown as a ball and stick model in black.
