Novel lineage‐specific transmembrane β‐barrel proteins in the endoplasmic reticulum of Entamoeba histolytica

β‐barrel outer membrane proteins ( BOMP s) are essential components of outer membranes of Gram‐negative bacteria and endosymbiotic organelles, usually involved in the transport of proteins and substrates across the membrane. Based on the analysis of our in silico BOMP predictor data for the Entamoeba histolytica genome, we detected a new transmembrane β‐barrel domain‐containing protein, EHI _192610. Sequence analysis revealed that this protein...
