CC -!- FUNCTION: Component of the HPA decarboxylase that decarboxylates
CC phenylacetates with a hydroxyl group in the p-position. Active toward
CC 4-hydroxyphenylacetate and 3,4-dihydroxyphenylacetate, forming 4-
CC methylphenol and 4-methylcatechol, respectively. Is likely involved in
CC the catabolism of aromatic amino acids such as tyrosine fermentation.
CC 4-methylphenol (p-cresol) formation provides metabolic toxicity, which
CC allows an active suppression of other microbes and may provide growth
CC advantages for the producers in highly competitive environments (By
CC similarity). The small subunit is essential for enzymatic activity of
CC HPA decarboxylase, and seems also involved in the regulation of the
CC enzyme oligomeric state and catalytic activity (By similarity).
