CC   -!- FUNCTION: Catalyzes the decarboxylation of L-tyrosine to produce
CC       tyramine for methanofuran biosynthesis. Can also catalyze the
CC       decarboxylation of L-aspartate to produce beta-alanine for coenzyme A
CC       (CoA) biosynthesis. {ECO:0000255|HAMAP-Rule:MF_01610}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+) + L-tyrosine = CO2 + tyramine; Xref=Rhea:RHEA:14345,

CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01610};
CC   -!- PATHWAY: Cofactor biosynthesis; methanofuran biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_01610}.
CC   -!- PATHWAY: Cofactor biosynthesis; coenzyme A biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_01610}.
