FIG. 3.
UPGMA (unweighted-pair group method using arithmetic averages) dendrogram of similarities between bacterial salicylate hydroxylases. Genetic sources are given in the legend for Fig. 2. The amino acid sequence of the 4-aminobenzoate hydroxylase (4ABH) of Agaricus bisporus Ab5341 (41) was used as an outgroup. The bar indicates 10% estimated sequence divergence. Isoelectric points (pI) and molecular masses (MM) are based on the sequence data.
