Twisted β‐sheets, packed face to face, may be arranged in circular formation like blades of a propeller or turbine. This β‐pro‐peller fold has been found in three proteins: that in neuraminidase consists of six β‐sheets while those in methylamine dehydrogenase and galactose oxidase are composed of seven β‐sheets. A model for multisheet packing in the β‐propeller fold is proposed. This model gives both geometrical parameters of the β‐propellers composed of different numbers of sheets and… 
Structural plasticity of a designer protein sheds light on β‐propeller protein evolution
Findings show that the β‐propeller fold allows sufficient structural plasticity to permit a given blade to assemble different forms, a transition from even to odd changes in blade number, and provide a potential explanation for the wide diversity of repeat numbers observed in natural propeller proteins.
Electrostatic and Functional Analysis of the Seven-Bladed WD β-Propellers
It is shown that it is possible to assign seven-bladed WD β-propeller proteins into functionally different groups based on the information gained from homology modelling, and the importance of structural data and the usefulness of homology models in functional classification is reinforced.
Structure and Stability of the designer protein WRAP-T and its permutants
Geometrical analysis of this protein and other artificial symmetrical proteins reveals no systematic constraint that could be used to help in engineering of this fold, and suggests sequence constraints unique to each β-propeller sub-family.

Folding of the N-terminal, ligand-binding region of integrin α-subunits into a β-propeller domain
The N-terminal ≈440 aa of integrin α subunits contain seven sequence repeats that are predicted here to fold into a β-propeller domain, which appears to be the most closely related G-protein β subunit.
Functional β-propeller lectins by tandem duplications of repetitive units.
The ability to construct folded and functional globular repeat proteins, and support the role of duplication and fusion of elementary modules in the evolutionary routes that led to the β-propellers fold are demonstrated.
Folding of the β-propeller domain of the integrin αL subunit is independent of the I domain and dependent on the β2 subunit
The results show that the I domain and β-propeller domains fold independently of one another, and suggest that the β- Propeller domain bears an interface for association with the β subunit.

This model shows how the observed relative orientation of two packed beta-sheets is a consequence of the rows of side chains at the interface being approximately aligned and the beta-sheet having a right-handed twist.
Structure of quinoprotein methylamine dehydrogenase at 2.25 A resolution.
The three‐dimensional structure of quinoprotein methylamine dehydrogenase from Thiobacillus versutus has been determined at 2.25 A resolution by a combination of multiple isomorphous replacement,
The beta bulge: a common small unit of nonrepetitive protein structure.
The functional roles of beta bulges probably include compensating for the effects of a single-residue insertion or deletion within beta structure and providing the strong local twist required for form closed beta barrel structures.

Structure of the influenza virus glycoprotein antigen neuraminidase at 2.9 Å resolution
The tetrameric enzyme has circular 4-fold symmetry stabilized in part by metal ions bound on the symmetry axis, and sugar residues are attached to four of the five potential glycosylation sequences, and in one case contribute to the interaction between subunits in the tetramer.
Structure of proteins: packing of alpha-helices and pleated sheets.
Simple models are presented that describe the rules for almost all the packing that occurs between and among alpha-helices and pleated sheets, which are the major determinants of the three-dimensional structure of proteins.
Novel thioether bond revealed by a 1.7 Å crystal structure of galactose oxidase
A unique structural feature at the copper site with a novel thioether bond linking Cys 228 and Tyr 272 in a stacking interaction with Trp 290 is revealed, which may represent a new mechanism for mediating electron transfer in metalloenzymes in the absence of exogenous cofactors.
