REVERSING THE SEQUENCE OF THE GCN4 LEUCINE ZIPPER DOES NOT AFFECT ITS FOLD.

Overview

The question of whether a protein whose natural sequence is inverted, adopts a stable fold is still under debate. We have determined the 2. 1-A, crystal structure of the retro-GCN4 leucine zipper. In contrast to the, two-stranded helical coiled-coil GCN4 leucine zipper, the retro-leucine, zipper formed a very stable, parallel four-helix bundle, which now lends, itself to further structural and functional studies.

About this Structure
