Activity of thymidine kinase during the cell cycle in Tetrahymena pyriformis
Abstract:
The presence of thymidine kinase has recently been reported in Tetrahymena pyriformis. The activity pattern for this enzyme was investigated during the cell cycle in both the one heat-shock per cell generation and the starvation-refeed system. Thymidine kinase was found to be a peak enzyme during S-phase in both situations. Nucleoside phosphotransferase was a continuous enzyme in the one heat-shock per cycle system, however, it closely paralleled the thymidine kinase curve during starvation and refeeding.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
