Abstract Metazoans use silicon traces but rarely develop extensive silica skeletons, except for the early-diverging lineage of sponges. The mechanisms underlying metazoan silicification remain incompletely understood, despite significant biotechnolog

Glassin is a water-soluble protein from the siliceous skeleton of a marine sponge that adsorbs tightly to silica at pH 7.0-9.0 and accelerates silica particle formation from silicic acid. Glassin comprises three distinct domains: a His and Asp-rich (

Identification of the Domains Involved in Promotion of Silica Formation in Glassin, a Protein Occluded in Hexactinellid Sponge Biosilica, for Development of a Tag for Purification and Immobilization of Recombinant Proteins

Publikováno v: Marine biotechnology (New York, N.Y.). 22(6)

Glassin, a protein occluded in biosilica of the hexactinellid sponge Euplectela, promotes silica formation from silicic acid at room temperature and neutral pH and is characterized by its primary structure which consists of a tandem repeat carrying t
