【 摘 要 】

The crystal structures of C-phycocyanin from Mastigocladus laminosus and Agmenellum quadruplicatum have been reinvestigated to accommodate the recently found γ-N-methylasparagine residue at β-72. In both structures, position β-72 could be modelled as γ-N-methylasparagine. The molecular phycocyanin structures were corrected accordingly. Possible roles of γ-N-methylasparagine are discussed on the basis of the three-dimensional structure.
