A likely scenario of evolution of biosynthetic pathways is believed to have occurred by retro-evolution through recruitment of existing enzymes rather than generation of de novo classes. It had been proposed that such retro-evolution occurred in steps as a response to depletion of an essential metab
## Abstract The culture of Nil hamster fibroblasts in MEM lacking nicotinamide (NAm^โ^ MEM) leads to: (1) the rapid loss of intracellular total nicotinamide adenine dinucleotide (NAD(H)) content in these cells from a level of 150โ200 pmoles/10^5^ cells to less than 20 pmoles/10^5^ cells; (2) the ce
