α/β barrel structures very similar to that first observed in triose phosphate isomerase are now known to occur in 14 enzymes. To understand the origin of this fold, we analyzed in three of these proteins the geometry of the eight‐stranded β‐sheets and the packing of the residues at the center of the barrel. The Packingin thisregion is seen in its simplest form in glycolate oxidase. It consists of 12 residues arranged in three layers. Each layer contains four side chains. The packing of RubisCO… 

On the evolution of alternate core packing in eightfold β/α‐barrels

It is demonstrated that simple genetic alterations may be responsible for switching the nature of side‐chain packing observed in β/α‐barrels and that convergent evolution to a stable fold need not be invoked to account for the emergence of 2 classes of β/β-barrel core.

Recurrent αβ loop structures in TIM barrel motifs show a distinct pattern of conserved structural features

The results suggest furthermore that conserved hydrophobic residues along the sequence of the connections, may be correlated more with specific patterns of interactions made with neighboring helices and sheet strands than with helix/strand packing within the connection itself.

Identifying the structural boundaries of independent folding domains in the a subunit of tryptophan synthase, a β/α barrel protein

Results suggest that the residual structure in αTS requires the participation of hydrophobic residues in multiple β‐strands that span the entire sequence, suggesting the modular assembly of βαβ supersecondary structural elements.

Locating the stabilizing residues in (α/β)8 barrel proteins based on hydrophobicity, long‐range interactions, and sequence conservation

This work proposes a new consensus approach for locating stabilizing residues in TIM‐barrel domains based on long‐range interactions, hydrophobicity, and conservation of amino acid residues, and suggests that these residues are among the ones with less mobility in the considered proteins.

Analysis of interactive packing of secondary structural elements in α/β units in proteins

The β‐sheet unit (βu), defined as a pair of adjacent parallel or antiparallel hydrogen‐bonded β‐strands, packing with an α‐helix shows a better correlation between the interaxial distance and log (V/nda) for the residues in the packing interface.

Arguments are made to support the divergence of all members of this family from a common ancestor and evidence is presented to suggest that convergent molecular evolution occurs when there is only one energetically reasonable pathway for a chemical reaction.

Packing constraints of hydrophobic side chains in (α/β)8 barrels

An analysis of possible tight packing of hydrophobic groups simultaneously at the both surfaces of β‐hyperboloid‐8 was conducted. This analysis shows that the disposition of amino acid side chains at
