AmiGO 2: Term Details for "porin activity" (GO:0015288)

Accession: GO:0015288
Name: porin activity
Ontology: molecular_function
Synonyms: porin, outer membrane exporter porin
Alternate IDs: None
Definition: Enables the transfer of substances, sized less than 1000 Da, from one side of a membrane to the other. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria.
