Title: A Suite of Engineered GFP Molecules for Oligomeric Scaffolding

Abstract

Applications ranging from synthetic biology to protein crystallization could be advanced by facile systems for connecting multiple proteins together in predefined spatial relationships. One approach to this goal is to engineer many distinct assembly forms of a single carrier protein or scaffold, to which other proteins of interest can then be readily attached. In this work we chose GFP as a scaffold and engineered many alternative oligomeric forms, driven by either specific disulfide bond formation or metal ion addition. We generated a wide range of spatial arrangements of GFP subunits from 11 different oligomeric variants, and determined their X-ray structures in a total of 33 distinct crystal forms. Furthermore, some of the oligomeric GFP variants show geometric polymorphism depending on conditions, while others show considerable geometric rigidity. Potential future applications of this system are discussed.

Structure-based design of a disulfide-linked oligomeric form of the simian virus 40 (SV40) large T antigen DNA-binding domain

Journal Article Meinke, Gretchen ; Phelan, Paul ; Fradet-Turcotte, Amélie ; ... - Acta Crystallographica. Section D: Biological Crystallography

With the aim of forming the ‘lock-washer’ conformation of the origin-binding domain of SV40 large T antigen in solution, using structure-based analysis an intermolecular disulfide bridge was engineered into the origin-binding domain to generate higher order oligomers in solution. The 1.7 Å resolution structure shows that the mutant forms a spiral in the crystal and has the de novo disulfide bond at the protein interface, although structural rearrangements at the interface are observed relative to the wild type.

Structure-based Design of a Disulfide-lined Oligomeric Form of the Simian Virus 40 (SV40) Large T Antigen DNA-Binding Domain

Journal Article Meinke, G ; Phelan, P ; Fradet-Turcotte, A ; ... - Acta Crystallographica Section D: Biological Crystallography

The modular multifunctional protein large T antigen (T-ag) from simian virus 40 orchestrates many of the events needed for replication of the viral double-stranded DNA genome. This protein assembles into single and double hexamers on specific DNA sequences located at the origin of replication. This complicated process begins when the origin-binding domain of large T antigen (T-ag ODB) binds the GAGGC sequences in the central region (site II) of the viral origin of replication. While many of the functions of purified T-ag OBD can be studied in isolation, it is primarily monomeric in solution and cannot assemble into hexamers. Tomore »« less

Selection of antigenic markers on a GFP-C{kappa} fusion scaffold with high sensitivity by eukaryotic ribosome display

Journal Article Yongmin, Yang ; IgE Therapeutics, Inc., San Diego, CA 92121-2233 ; Barankiewicz, Teresa J ; ... - Biochemical and Biophysical Research Communications

Ribosome display is a cell-free system permitting gene selection through the physical association of genetic material (mRNA) and its phenotypic (protein) product. While often used to select single-chain antibodies from large libraries by panning against immobilized antigens, we have adapted ribosome display for use in the 'reverse' format in order to select high affinity antigenic determinants against solid-phase antibody. To create an antigenic scaffold, DNA encoding green fluorescent protein (GFP) was fused to a light chain constant domain (C{kappa}) with stop codon deleted, and with 5' signals (T7 promoter, Kozak) enabling coupled transcription/translation in a eukaryotic cell-free system.

Zinc and the iron donor frataxin regulate oligomerization of the scaffold protein to form new Fe–S cluster assembly centers

Journal Article Galeano, B. K. ; Ranatunga, W. ; Gakh, O. ; ... - Metallomics

Early studies of the bacterial Fe–S cluster assembly system provided structural details for how the scaffold protein and the cysteine desulfurase interact. This work and additional work on the yeast and human systems elucidated a conserved mechanism for sulfur donation but did not provide any conclusive insights into the mechanism for iron delivery from the iron donor, frataxin, to the scaffold. We previously showed that oligomerization is a mechanism by which yeast frataxin (Yfh1) can promote assembly of the core machinery for Fe–S cluster synthesis both in vitro and in cells, in such a manner that the scaffold protein, Isu1,more »« less

Full-Length Structures of BenM and Two Variants Reveal Different Oligomerization Schemes for LysR-Type Transcriptional Regulators

Journal Article Ruangprasert, Ajchareeya ; Craven, Sarah H ; Neidle, Ellen L ; ... - J. Mol. Biol.

BenM, a LysR-type transcriptional regulator (LTTR) from the bacterium Acinetobacter baylyi, responds synergistically to benzoate and cis,cis-muconate. With these effectors, BenM activates gene expression during benzoate consumption. Without effectors, BenM represses transcription. Here, X-ray crystallography was used to determine the full-length structures of BenM and two variants that activate transcription without benzoate or cis,cis-muconate: BenM(R156H) and BenM(E226K). Previous studies indicate that these regulators function as tetramers. Here, interconnections between subunits in the crystals prevented the formation of a closed oligomer and highlighted the inherent flexibility of this multidomain regulator. Nevertheless, analysis of subunit interfaces suggested the functional significance of keymore »« less
