Cadmium toxicity in plants - SciELO
Enzymes are one of the main targets of heavy metal ions and prolonged exposure of soils to heavy metals results in marked decreases in soil enzymes activity (Tyler et al., 1989). Metal interaction with ligand groups of enzymes largely defines their toxicity, and the inhibition of enzymes may be due to masking of alytically active groups or protein denaturation (Das et al., 1997).
