|Gene:||rdoA||Accession Numbers: EG11831 (EcoCyc), b3859, ECK3851|
Synonyms: orfA, yihE
YihE is a serine/threonine protein kinase that is able to autophosphorylate at serine and threonine, but not tyrosine residues. YihE is also able to phosphorylate the general kinase substrate, myelin basic protein, in vitro. The native substrate for YihE has not been identified yet [Zheng07]. yihE is a target gene activated by the Cpx pathway that senses envelope stress [Belin94, Pogliano97].
A D217A mutation abolishes catalytic activity [Zheng07]. A yihE insertion mutation decreases the abundance of periplasmic DsbA (which is the product of the gene directly downstream of yihE), but does not appear to affect periplasmic disulfide bond formation [Belin94].
YihE has similarity to Salmonella enterica serovar Typhimurium RdoA, which affects flagellation and dsbA transcription via effects on signal transduction by the Cpx stress response pathway [Suntharalingam03], and to Shigella flexneri YihE, which appears to be involved in a cellular stress response [Li01].
A crystal structure of YihE has been determined at 2.8 Å resolution and shows similarity to protein kinases [Zheng07].
