All metabolic pathways have to be regulated and controlled to stop the build-up of an end product that isn’t needed. The cell can control a metabolic pathway by the presence or absence of a particular ...

Researchers have discovered how sperm cells perform an extraordinary metabolic transformation after ejaculation, from quiet ...

We used a pale-green maize (Zea mays L.) mutant that fails to accumulate ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) to test the working hypothesis that the regulatory phosphorylation of ...
