In molecular biology group IV pyridoxal-dependent decarboxylases are a family of enzymes comprising ornithine decarboxylase EC 4.1.1.17 lysine decarboxylase EC 4.1.1.18 arginine decarboxylase EC 4.1.1.19 and diaminopimelate decarboxylaseEC 4.1.1.20. It is also known as the Orn/Lys/Arg decarboxylase class-II family.Pyridoxal-5′-phosphate-dependent amino acid decarboxylases can be divided into four groups based on amino acid sequence.
