Rapid Ventricular Filling

The rapid flow of blood from the atria to the ventricles produces the third heart sound (S3).

Cyclization between Ser and Gly is probably rapid, and the oxidation of the Tyr side chain (by O2) is probably the rate-limiting step of fluorophore generation.

Upon absorbing UV-B photons, the tryptophans undergo structural changes that break the salt bridges, leading to the dissociation of the two functionally active monomers. The monomers then interact with COP1–SPA complexes to activate gene expression

dat locus is regulatory

In particular, a locus called dat has a large concentration of DnaA-binding sites. It binds about 80 more DnaA molecules than the origin.

Deletion of dat causes initiation to occur more frequently. This significantly increases the amount of DnaA available to the origin.
