Chains	Enzyme Name	Description	Catalytic Residues
A	ornithine decarboxylase M-CSA #937	Ornithine decarboxylase is a PLP-dependent enzyme that catalyses the first and rate-limiting step of polyamine biosynthesis that converts ornithine into putrescine, which is the precursor for the polyamines, spermidine and spermine. Polyamines are essential for cell proliferation and are implicated in cellular processes, ranging from DNA replication to apoptosis.
