  • Title: Biochemistry: a cadmium enzyme from a marine diatom.
    Author: Lane TW, Saito MA, George GN, Pickering IJ, Prince RC, Morel FM.
    Journal: Nature; 2005 May 05; 435(7038):42. PubMed ID: 15875011.
    Abstract:
    The ocean biota contains a vast reservoir of genomic diversity. Here we present the sequence and preliminary characterization of a protein that is a cadmium-containing carbonic anhydrase from the marine diatom Thalassiosira weissflogii. The existence of a cadmium enzyme in marine phytoplankton may indicate that there is a unique selection pressure for metalloenzymes in the marine environment, and our discovery provides a long-awaited explanation for the nutrient-like behaviour of cadmium in the oceans.
