Pf-SCP, a 21 kDa protein with two EF-hand motifs and a phosphorylation site, was identified from mantle tissue and binds to calcium ions and transports calcium components from cell to the shell of Pinctada fucata. To reveal the molecular basis of the calcium binding activity of Pf-SCP, we expressed the recombinant protein of full-length Pf-SCP in Escherichia coli. Recombinant Pf-SCP (rPf-SCP) purified by Ni affinity chromatography and size exclusion chromatography appeared as a single band on SDS-PAGE. The circular dichroism spectros
