Term Information [More information on porin activity]

Accession
GO:0015288
Name
porin activity
Ontology
molecular_function
Synonyms
porin, outer membrane exporter porin
Definition
Catalysis of the transfer of substances, sized less than 1000 Da, from one side of the 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.
