At the beginning of this reaction, 1 molecule of '2-Amino-3-carboxymuconate semialdehyde' is present. At the end of this reaction, 1 molecule of 'CO2', and 1 molecule of '2-Aminomuconate semialdehyde' are present.
This reaction takes place in the 'cytoplasm' and is mediated by the 'carboxy-lyase activity' of '2-amino-3-carboxymuconate-6-semialdehyde decarboxylase homodimer'.
