Figure 1From: Crystal structure of the Habc domain of neuronal syntaxin from the squid Loligo pealei reveals conformational plasticity at its C-terminusAsymmetric unit content in crystals of neuronal syntaxin from L. pealei (A) Ribbon diagram of the dimer in the asymmetric unit. N- and C-terminal ends are indicated. A brace indicates the C-terminal Habc region (in molecule B), which can have either helical or extended conformation. (B) Overlay of the Cα backbone of molecules A and B. Note that the C-terminus of molecule A deviates from the helical fold of Hc from molecule B as 4 helical turns are unwound.Back to article page
