title: Cloning, expression and sequence analysis of cDNA for the Ca(2+)-binding photoprotein, mitrocomin.
abstract: The primary structure of mitrocomin consists of 190 amino acid residues, with three Ca(2+)-binding sites and a tyrosine residue at the C-terminus. Mitrocomin shows an amino acid sequence homology of 67.9% and 60.7% when compared with aequorin and clytin, respectively. The amino acid residues Cys152, His58, His169, Trp12, Trp86, Trp108, Trp129 and Trp173 are conserved in all three photoproteins, suggesting that they play a role in light emission.
