A structural analysis of the regularly arranged porin on the outer membrane of Campylobacter jejuni based on correlation averaging.
A negatively stained electron micrograph of regularly arranged porin proteins of Campylobacter jejuni on the isolated outer membrane of bacteria was analyzed in detail by the correlation averaging method using a computer-assisted program. The results showed that the porin of C. jejuni had a trimeric structure separated by about 10.4 +/- 0.15 nm. In addition, the pores in the trimers were also separated by about 4.3 +/- 0.1 nm.
