300px, Ribbon diagram of CheY (a regulator of the chemotactic response in bacteria, PDB accession code 3CHY), which adopts the flavodoxin fold. Ribbon is colored from blue (N-terminus) to red (C-terminus).
The flavodoxin fold is a common α/β protein fold, second only to the TIM barrel fold. It has three layers, with two alpha helix, α-helical layers sandwiching a 5-stranded parallel
β-sheet
The beta sheet (β-sheet, also β-pleated sheet) is a common structural motif, motif of the regular protein secondary structure. Beta sheets consist of beta strands (β-strands) connected laterally by at least two or three backbone chain, backbon ...
. The order of strands within the sheet is 2-1-3-4-5.
This motif is present for example in lactate dehydrogenase () or phosphoglycerate kinase ().
