Phosphate-starvation-induced PsiE-like

InterPro entry
Short nameP_starv_induced_PsiE-like
family relationships

Description

This entry represents the phosphate-starvation-inducible protein (PsiE) and similar proteins. This entry is sometimes found in proteins that contain other domains such as the protoglobin domain.

Phosphate-starvation-inducible E (PsiE) expression is under direct positive and negative control by PhoB and cAMP-CRP, respectively
[1]
. PsiE is an integral membrane protein with four transmembrane helices. The second α helix contains a conserved glutamic acid residue and the third helix contains a conserved arginine residue. The function of PsiE remains to be determined.
