The ethanolamine facilitator EutH, of 408 aas and 11 or 12 TMSs.  The E. coli orthologue (P76552) is identical to the S. enterica protein. They are probably involved in the diffusion of protonated ethanolamine (EA) into the cell at low pH where most EA is protonated, and this permease becomes necessary. It contributes to bacterial survival and replication in acidified macrophage vacuoles (Anderson et al. 2018). It is associated with a bacterial ethanol metabolizing bacteria microcompartment, Eut1 (Kirst and Kerfeld 2021).
