Architecture and regulatory functions of c-di-GMP signaling in classical Bordetella species.

ABSTRACT: Cyclic di-GMP (c-di-GMP) is a highly conserved bacterial second messenger that regulates important processes such as motility, biofilm formation and virulence. In this review, we investigate the architecture and regulatory functions of c-di-GMP signaling in classical Bordetella species, including B. bronchiseptica, B. parapertussis and B. pertussis. We examine how the c-di-GMP signaling pathway interacts with the BvgAS two-component system and other signaling pathways to coordinate virulence gene expression and surface-associated behaviors in these respiratory pathogens. In particular, we highlight the functions of characterized diguanylate cyclases (DGCs), phosphodiesterases (PDEs) and dual-domain proteins, focusing on regulatory modules such as the BdcA-DdpA scaffold complex, the oxygen-
