AbstractBrachiopods are a phylum of marine invertebrates that have an external bivalved shell to protect their living tissues. With few exceptions, this biomineralized structure is composed of calcite, mixed together with a minor organic fraction, comprising secreted proteins that become occluded in the shell structure, once formed. This organic matrix is thought to display several functions, in particular, to control mineral deposition and to regulate crystallite shapes. Thus, identifying the primary structure of matrix proteins is a prerequisite for generating bioinspired materials with tailored properties. In this study, we employed a proteomic approach to identify numerous peptides that constitute the shell proteins, in three rhynchonellid brachiopods from different localities. Our results suggest that the shell protein repertoires identified thus far, differ from that of better known calcifying metazoans, such as molluscs. © 2015 Elsevier Inc.
