Deletion variants of Neurospora mitochondrial porin: electrophysiological and spectroscopic analysis.

Abstract excerpt

Mitochondrial porins are predicted to traverse the outer membrane as a series of beta-strands, but the precise structure of the resulting beta-barrel has remained elusive. Toward determining the positions of the membrane-spanning segments, a series of small deletions was introduced into several of the predicted beta-strands of the Neurospora crassa porin. Overall, three classes of porin variants were identified:...
