Deduced amino acid sequence of bovine aromatic L-amino acid decarboxylase: homology to other decarboxylases.
Nucleotide sequence of cDNA for bovine aromatic L-amino acid decarboxylase (AADC) was analyzed. The deduced amino acid sequence of bovine AADC shows 57% identity to drosophila AADC and 37% to plant Catharanthus roseus AADC. The 7-amino acid sequence of the pyridoxal phosphate binding site is completely conserved among drosophila, pig and bovine AADC. AADC primary structure also shows high homology to that of feline glutamic acid decarboxylase.
