Nucleation clusters. In calcium phosphate solution, the presence of amelogenin stabilized small particles, aggregates with two or three particles and larger aggregates (pre-nucleation clusters). While needle shaped particles of hydroxyapatite were eventually formed, the amorphous aggregates were stabilized by amelogenin, leading to the statement that amelogenin inhibited (retarded) mineralization
Tructures on binding. 2.4 Self-Assembly of IDPs IDPs frequently undergo self-assembly. The extended conformation of IDPs facilitates the intermolecular interactions between them and promotes formation of supramolecular architecture [109]. This is illustrated in some of the mineralized tissues discussed above. Silaffins, for example, are protein constituents of biosilica, playing an active role in

Ly differ from those observed with interactions with calcium phosphate mineral [113]. In vitro studies with amelogenin reported a disorder-to-order transition during the self-assembly process. The amelogenin molecules at pH 7.2 spontaneously self-assemble into oligomers and nanospheres. These subsequently bind together to form micro-ribbons [58]. Beniash et al suggest that this amelogenin self-as

To illustrate, salivary stones occur when mucins, such as statherin, an un-folded protein [63],
