Figure 7

Alignment of the amino acid sequences of phytochelatin synthase fragments isolated from Amphora acutiuscula (FN995989), Amphora coffeaeformis (FN995985), Entomoneis paludosa (FN995987) and Nitzschia palea (FN995985) grown in ASW. Black boxes indicated 100% identity, dark grey 80%, and light grey 60%. The cysteine residues are indicated by asterisks.
