Biofunctional change in yeast cell surface on treatment with triton X-100.

In our studies on fermentative production of sugar nucleotides and cytidine derivatives,1 ~6) we found that Triton X-100 treatment of yeast cells allowed them to phosphorylate nucleotide monophosphate (CMP)to nucleotide triphosphate (CTP) and then, convert them further to a final nucleotide derivative (CDP-choline).
