Abstract

A protein identifiable as calmodulin has been isolated from the fruit tissue of Citrus sinensis (cv. Valencia). This protein is relatively heat-stable, binds to hydrophobic gels in a calcium-dependent fashion and to antibody against rat testis calmodulin, and stimulates calmodulin-deficient cAMP phosphodiesterase. The protein has an isoelectric point of 3.7 and M_rs of 14500 and 17000 in the presence and absence of Ca²⁺, respectively. Based on its migration on SDS-PAGE gels, its UV absorption spectrum and its amino acid composition, calmodulin from citrus fruit is essentially identical to calmodulin isolated from other plant tissues, e.g. leaves and seeds.
