CC -!- FUNCTION: Catalyzes the first and rate-limiting step of polyamine
CC biosynthesis that converts ornithine into putrescine, which is the
CC precursor for the polyamines, spermidine and spermine. Polyamines are
CC essential for cell proliferation and are implicated in cellular
CC processes, ranging from DNA replication to apoptosis.
CC {ECO:0000256|ARBA:ARBA00037173}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + L-ornithine = CO2 + putrescine; Xref=Rhea:RHEA:22964,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:46911,
CC ChEBI:CHEBI:326268; EC=4.1.1.17;
CC Evidence={ECO:0000256|ARBA:ARBA00034037};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|PIRSR:PIRSR600183-50};
CC -!- PATHWAY: Amine and polyamine biosynthesis; putrescine biosynthesis via
CC L-ornithine pathway; putrescine from L-ornithine: step 1/1.
CC {ECO:0000256|ARBA:ARBA00034115}.
CC -!- SIMILARITY: Belongs to the Orn/Lys/Arg decarboxylase class-II family.
CC {ECO:0000256|RuleBase:RU003737}.
