Abstract

Cadmium-Peptides Complexes in Dunaliella salina Cells

Moh. Muhaemin

Dunaliella salina responds to cadmium present in cells by synthesizing phytochelatin. Reverse Phase (RP)
and common HPLC analysis describe the formation of complexes between Cd and γ-glutamyl peptides in
cells. The unique peptides chain chelate Cd by thiolate bonds formation. Two classes of Cd-PCn complexes
were identified as specific Cd-peptides complexes binding in D. salina.
