| Authors: | A Dierich M Wintzerith P Mandel |
| Abstract: | Important amounts of nicotinic acid appear in the growth medium of neuroblastoma cell cultures. It is shown that an enzyme released by the cells into the growth medium deamidates the nicotinamide supplied by the growth medium to nicotinic acid. |
