Outer membrane porin D is a
protein family containing bacterial
outer membraneporins which are involved in transport of cationic amino acids, peptides, antibiotics and other compounds.
It was also described as having some
serine protease activity.[1] However many of these
proteins are not peptidases and are classified as non-peptidase
homologues as they either have been found experimentally to be without peptidase activity, or lack
amino acidresidues that are believed to be essential for the
catalytic activity of peptidases in the S43 family.
