FHIPEP protein family (original) (raw)
In molecular biology, the FHIPEP protein family (Flagellar/Hr/Invasion Proteins Export Pore family)consists of a number of proteins that constitute the type III secretion (or signal peptide-independent) pathway apparatus. This mechanism translocates proteins lacking an N-terminal signal peptide across the cell membrane in one step, as it does not require an intermediate periplasmic process to cleave the signal peptide. It is a common pathway amongst Gram-negative bacteria for secreting toxic and flagellar proteins.
