| porin | <protein> Transmembrane matrix proteins (37 kD) found in the outer membranes of gram-positive bacteria. Associate as trimers to form channels (1 nm diameter, ca 10exp5 per bacterium) through which hydrophilic molecules of up to 600D can pass. Similar porins are also found in outer mitochondrial membranes (VDAC, voltage dependent anion selective channel). (14 Oct 1997) |

| porins | Protein molecules situated in the outer membrane of bacteria that, in dimeric or trimeric form, constitute a water-filled transmembrane channel allowing passage of ions and other small, relatively non-specific molecules. Porins are also found in mitochondria and plants. (12 Dec 1998) |
