Publication Abstract from PubMed
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.
The retro-GCN4 leucine zipper sequence forms a stable three-dimensional structure.,Mittl PR, Deillon C, Sargent D, Liu N, Klauser S, Thomas RM, Gutte B, Grutter MG Proc Natl Acad Sci U S A. 2000 Mar 14;97(6):2562-6. PMID:10716989[1]
