[[Porin]] or '''Outer Membrane Proteins''' '''(Omps)''' act as channels which allow passive diffusion of sugars, ions and amino acids. They are beta barrel proteins which traverse the cell membrane. In ''E. coli'' they are named according to their genes: C, F, G (OmpC, OmpF, OmpG).

Voltage-Dependent Anion Channel (VDAC) are ion channel Omps found in outer mitochondrial membrane. In Pseudomonas aeruginosa the porin gene products are named OprD, OprE, OprK, OprP. '''Maltoporin''' (LamB) facilitates the diffusion of maltodextrin across the membrane. See more details in<br /> | ||
