Novel silica forming peptide, RSGH, from Equus caballus: Its unique biosilica formation under acidic conditions

A novel silica forming peptide (SFP), RSGH was designated on the basis of the peptide found from Equus caballus and investigated for its ability to precipitate biosilica under acidic conditions, where biosilica is not easily formed. At pH values of 4, 5 and 6, RSGH showed better performance in the generation of silica particles than the most well-known SFP, silaffin R5, and the amount of the produced biosilica particles increased with the...
