LociOiling's crambin from puzzle 1305, an electron density puzzle.

76: Plant Seed Protein is a revisiting puzzle, originally presented in 2009 as Puzzle 76: Plant Seed Protein.

The protein in this puzzle is crambin, a seed storage protein from Abyssinian cabbage. This small protein has been studied extensively, since its structure yields very precise results with X-ray crystallography.

The puzzle has 46 segments with the sequence:


This sequence is found in many Protein Data Bank entries:

  • 4FC1 (chain A, offset 0)
  • 3NIR (chain A, offset 0)
  • 2FD9 (chain A, offset 0)
  • 2FD7 (chain A, offset 0)
  • 2EYD (chain A, offset 0)
  • 2EYC (chain A, offset 0)
  • 2EYB (chain A, offset 0)
  • 2EYA (chain A, offset 0)
  • 1VYA (chain A, offset 0)
  • 1VY8 (chain A, offset 0)
  • 1EJQ (chain A, offset 0)
  • 1CNR (chain A, offset 0)
  • 1CCN (chain A, offset 0)
  • 1CCM (chain A, offset 0)
  • 1CRN (chain A, offset 0)

This puzzle can have three disulfide bridges.

The recipe Bridge Wiggle v 1.2.1 - Brow42 accepts the bridges in this format:

3,40 16,26 4,32 

This puzzle does not have any ligands.

This puzzle has a single chain.
