β-[U-14C]Alanine can be synthesized in >95% yield from l-[U-14C]aspartic acid using the aspartate 1-decarboxylase of Escherichia coli and converted to d-[1,2,3-14C]pantothenate in a 10–20% yield using the pantothenate synthetase of E. coli. Sufficiently pure preparations of both enzymes are readily obtained.
