InterPro domain: IPR019626

This repeat contains a highly conserved, characteristic sequence motif, KGG, that is recognised by plants and lower eukaryotes.Further downstream from this motif is a Walker A, nucleotide binding motif. YciG is expressed as part of a three-gene operon, yciGFE and this operon is induced by stress and is regulated by RpoS, which controls the general stress-response in E coli. YciG was shown to be important for stationary-phase resistance to thermal stress and in particular to acid stress [ 1 ].
