Regulation summary diagram for yegE

YegE is a GGDEF/EAL protein that is involved in regulation of the switch from flagellar motility to sessile behavior and curli expression [Pesavento08].

YegE has a MASE1 (Membrane-Associated SEnsor) domain, which includes eight putative membrane segments and is found in proteins associated with signal transduction [Nikolskaya03].

A mutation in yegE partially suppresses the motility defect of a yhjH mutant at 28°C [Pesavento08], suggesting that YegE is one of four diguanylate cyclases that adjust c-di-GMP concentration for motility control [Boehm10]. yegE mutants show reduced expression of curli, possibly due to an effect on transcription of csgD [Pesavento08]. A mutation in yegE was shown to affect csgB expression [Sommerfeldt09].

Expression of yegE increases during the transition to stationary phase and is dependent on σS [Pesavento08, Sommerfeldt09].
