Formyltetrahydrofolate synthase from Clostridium thermoaceticum. An electron microscopic study and specific interaction of the enzyme with ATP and ADP.

Formyltetrahydrofolate synthetase (EC 6.3.4.

Properties of enzymes from Clostridium thermoaceticum and Clostridium formicoaceticum.

Methylenetetrahydrofolate dehydrogenase from C. thermoaceticum and C. formicoaceticum have been purified to homogeneity and compared.

The phosphorylation region of lysine-rich histone in dividing cells.

N-Bromosuccinimide cleavage of in vivo 32P-labelled lysine-rich histone isolated from rapidly dividing cells has been studied. N-Bromosuccinimide cleaves F1-histone into two fragments, a small N-terminal piece and a larger C-terminal portion. The phosphate-induced microheterogeneity and associated radioactivity which has been linked to cell replication, is found in the carboxyterminal fragment, No phosphorous is found associated with the amino-terminal fragment when histone phosphorylation is associated with cell division.
