Formation of Folate Enzymes during the Growth Cycle of Bacteria. I. Tetrahydrofolate Dehydrogenase Activity During the Lag and Acceleration Periods of Streptococcus faecalis R.

Abstract
The tetrahydrofolate dehydrogenase activity of S. faecalis-R increases during the first 2 growth phases, and does so from the very beginning of the lag phase. Therefore, it is considered a typical "lag-phase enzyme".
