Fig. 3From: Metagenomic analyses reveal phylogenetic diversity of carboxypeptidase gene sequences in activated sludge of a wastewater treatment plant in Shanghai, ChinaPhylogenetic tree of deduced carboxypeptidase amino acid sequences obtained from microbial community of activated sludge samples in industrial and municipal wastewater. Based on the 102 novel sequences ranged in size from 127 to 208 amino acid residues, the neighbor-joining tree was constructed by the MEGA 4.0 together with a selected set of the public carboxypeptidase sequences. The length of the branches indicates the divergence among the amino acid sequencesBack to article page
