Figure 1From: A novel esterase gene cloned from a metagenomic library from neritic sediments of the South China SeaUnrooted neighbor-joining phylogenetic tree of Est_p1 (red triangle) and relatives, based on conserved sequence motifs of bacterial lipolytic enzymes. Amino acid sequences of other lipolytic enzymes were obtained from published data. Sequence alignment was performed using ClustalW version 2.0, and the tree was created by MEGA version 4.0. Scale bar at bottom indicates number of amino acid substitutions per site.Back to article page
