Overall structural organization and multiple sequence alignment of CcEstA.
(A) The structural organization of CcEstA is compared with other related proteins in Caulobacter crescentus. Note that important catalytic residues (colored residues) are highly conserved and lie on spatially similar positions in each protein. (B) Multiple sequence alignment of CcEstA was performed with related proteins in C. crescentus using Clustal Omega and ESPript. Only three characteristic motifs of these proteins (motif I, II and III) are shown for clarity and highly conserved residues are shown in red.
