Summary
A divergon is a regulon comprised of two adjacent divergent operons or genes. [More information is available at EcoGene: EG12894]. In Escherichia coli, gspK is a member of an operon of genes (gspC-O) which are not normally expressed but are homologous to those encoding the secreton, or type II secretion machinery in Klebsiella oxytoca and Aeromonase hydrophila, among others . [More information is available at EcoCyc: G7710].
