Figure 3
Structure-based sequence alignment of alanine racemases from A. baumannii, E. coli, B. henselae and P. aeruginosa. Identical residues are shaded black, while grey shading indicates amino acids with conserved physicochemical properties. An asterisk marks the highly conserved PLP-bound lysine and a black diamond marks the location of the catalytic tyrosine, while a black circle indicates the location of a residue which is often carbamylated in alanine racemases that have a lysine at this position. The purple box encloses the conserved PLP-binding motif containing the catalytic lysine. The red box indicates the region of electron density missing from monomer B of AlrAba. I and M represent residues which form the inner and middle layers of the active-site entryway. |
