'''High resolution Structure determination of rhodocetin'''<br />


==Overview==
==Overview==
Rhodocetin is a unique heterodimer consisting of alpha- and beta-subunits, of 133 and 129 residues, respectively. The molecule, purified from the, crude venom of the Malayan pit viper, Calloselasma rhodostoma, functions, as an inhibitor of collagen-induced aggregation. Rhodocetin has been shown, to have activity only when present as a dimer. The dimer is formed without, an intersubunit disulfide bridge, unlike all the other Ca(2+)-dependent, lectin-like proteins. We report here the 1.9 A resolution structure of, rhodocetin, which reveals the compensatory interactions that occur in the, absence of the disulfide bridge to preserve activity.
