Comparative Analysis of Fatty Acid Desaturases in Cyanobacterial Genomes

Figure 12

Neighbor-joining tree of membrane desaturases. About 330 positions spanning the three histidine-boxes were employed. Sequences from 37 sequenced cyanobacterial genomes are shown by their acronyms and accession numbers (locus tags). Other sequences are shown by their accession numbers, labels, and strain names. Desaturase genes that have been functionally characterized are indicated on the tree by their labels. Bootstrap values from neighbor-joining analyses are listed to the left of each node, with values more than 50 are shown.
