Lineage for Family d.3.1.14: Phytochelatin synthase

1. Root: SCOPe 2.04

2. Class d: Alpha and beta proteins (a+b) [53931] (380 folds)

3. Fold d.3: Cysteine proteinases [54000] (1 superfamily) consists of one alpha-helix and 4 strands of antiparallel beta-sheet and contains the catalytic triad Cys-His-Asn

4. Superfamily d.3.1: Cysteine proteinases [54001] (23 families) the constitute families differ by insertion into and circular permutation of the common catalytic core made of one alpha-helix and 3-strands of beta-sheet

5. Family d.3.1.14: Phytochelatin synthase [142867] (1 protein) Pfam PF05023; assosiated Pfam PF09328 (DUF1984) is a part of the same functional unit
