Calcium binding properties of recombinant calcium binding protein 40, a major calcium binding protein of lower eukaryote Physarum polycephalum.

Abstract

Calcium binding protein 40 (CBP40) is a Ca(2+)-binding protein abundant in the plasmodia of Physarum polycephalum. CBP40 consists four EF-hand domains in the COOH-terminal half and a putative alpha-helix domain in the NH(2)-terminal half. We expressed recombinant proteins of CBP40 in Escherichia coli to investigate its Ca(2+)-binding properties. Recombinant… (More)
