It is also a receptor for the bacteriophage T2. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMed The attachment of modulators to a trimeric porin ion channel was investigated (see picture of the trimer with a crown ether modulator (orange)). The interplay of modulator and protein is essential for the conformational heterogeneity of the hybrid channel. Single-site attachment in large pores is not sufficient to change the electrophysiological characteristics of the pores-such change requires additional noncovalent interactions or second-site attachments.
