Statistical Analysis of Terminal Extensions of Protein β-Strand Pairs

Figure 1

An illustrated example of β-strand pairing in a β-sheet (PDB code: 1HZT). (a) The sketch of the tertiary structure of the protein produced by using RASMOL. Protein 1HZT is an α/β protein with 10 β-strands numbered from 1 to 10, forming seven different strand pairs. (b) The sequences of the 10 β-strands with their initial and ending residue numbers. (c) The 10 β-strands in the linear primary sequence. (d) An example of a β-strand partnership graph. The pairing is between strands “B3” and “B4,” with the light gray box representing the common pairing part.
