Fig. 2From: Sequence similarity network analysis, crystallization, and X-ray crystallographic analysis of the lactate metabolism regulator LldR from Pseudomonas aeruginosa Sequence alignment of LldR homologues from P. aeruginosa, E. coli, and C. glutamicum. PLldR, LldR from P. aeruginosa; ELldR, LldR from E. coli; CLldR, LldR from C. glutamicum. The highly conserved residues are indicated by asterisk. The residues involved in Zn2+-binding in LldR are indicated by hash. The completely conserved residues indispensable for DNA-binding are indicated by middle dot. The sequences were aligned with the program CLUSTAL_XBack to article page
