Figure 1.
Figure 1. Rhodocytin is an (  β)[2]
tetrameric C-type lectin-like snake venom protein. (A)
Rhodocytin forms a tetramer containing two copies of a disulfide
linked β-heterodimer,
whereas factor X-bp is dimeric, and convulxin is cyclic. - and
β-chains are colored yellow and pink, respectively. Disulfide
bonds in rhodocytin are colored green. (B) Each image represents
the molecular surface of one rhodocytin β-heterodimer
at the interface that forms the tetramer. In the upper panel,
the hydrophobic surface is colored green. In the lower panel,
negatively and positively charged regions are colored red and
blue, respectively, from –7 to +7 kTe. (C) Hydrogen bonds are
shown as broken blue lines between residues of the two -chains
within the rhodocytin tetramer. For clarity, one -chain is
colored yellow and the other red. For residues involved in
hydrogen bonds, carbon atoms are colored light blue, oxygen is
red, and nitrogen is dark blue.
