Figure 2From: A novel esterase gene cloned from a metagenomic library from neritic sediments of the South China SeaConserved sequence blocks from multiple sequence alignment between Est_p1 and family V members of known 3D structure. Sequence alignment was performed using ClustalW version 2.0 and ESPript programs. Conserved sequences are indicated by box, and similar sequences are indicated by colored background. The catalytic triads are identical (red triangle). The alpha helix, beta sheet, random coil and beta turn are identical to α, β, η and T, respectively.Back to article page
