decarboxylases

Enzymes that promote the freeing of COO from -COOH. These enzymes are involved in the synthesis of amine regulators and neurotransmitters such as serotonin and dopamine.

ABSTRACT--Aciduric, pH-elevating Bacillus, which cause non-effervescent spoilage of under-processed tomatoes, were shown to have an L-lysine decarboxylase optimally active at pH 5.
