Carbohydrate-selective porin OprB (IPR007049)

Short name: Carb-sel_porin_OprB

Overlapping homologous superfamilies

Family relationships



The carbohydrate-selective porin OprB family includes the Pseudomonas aeruginosa porin B, a substrate-selective channel for a variety of different sugars. This protein may facilitate diffusion of a variety of diverse compounds, but is probably restricted to carbohydrates, and does facilitate glucose fusion across the outer membrane.
