文摘
BackgroundThe secondary messenger cyclic di-GMP promotes biofilm formation by up regulating the expression of csgD, encoding the major regulator of rdar biofilm formation in Salmonella typhimurium. The GGDEF/EAL domain proteins regulate the c-di-GMP turnover. There are twenty- two GGDEF/EAL domain proteins in the genome of S. typhimurium. In this study, we dissect the role of individual GGDEF/EAL proteins for csgD expression and rdar biofilm development.
