Parts of LSCC that are active during endogenous condition (or, conditions with larger number of active cycles). Cell cycle: Interaction between 5 and 15 appears to repress stress response. Sporulation: Most of the cell cycle interactions are present, but the cycle interactions leaving node 25 are not. Replication of DNA is an activity shared with the cell cycle. Stress response: When we compare the part of LSCC that is active during stress response with parts of LSCC that are active during cell cycle and sporulation, we note that in the latter cases the stress response cycle is totally inactive, but it is partially active during the diauxic shift and DNA damage, which are related to stress (damage – obvious, diauxic shift – the shift toward less favored nutrition source). Center of the cell cycle is activated during stress response, which can be part of a repression mechanism.
