From: Computational prediction of Pho regulons in cyanobacteria
Genomic organization of alkaline phophosphatases and extracellular nuclease nucH genes in cyanobacteria. A vertical arrow indicates that three tandem Pho boxes are found for the predicted operon with p < 0.01. The order of the operons does not reflect their actual positions on the chromosome, but rather it is a schematic illustration of the operons. The label alk represents an alkaline phosphatase of an uncharacterized type.
