Interactions with neighbouring molecules in the form 1 and form 2 crystals around His68. (a) The 6-propionate group interacts with Lys10* of the neighbouring molecule in the crystal in the oxidized form 1 structure. (b) The 6-propionate group interacts with His32* in the oxidized form 2 structure. The main-chain carbonyl O atoms of Val66 and Gly67 also interact with Arg89*. The C atoms of the neighbouring molecules in the crystals are coloured grey in (a) and (b). Bond distances between N and O atoms (in Å) are indicated in the figures.
