The methionine cycle (MTC), also known as activated methionine cycle, is among those primary metabolic pathways affected by plant virus infection (reviewed in [1]). We found that PVA protein helper ...

In the transsulfuration pathway, Hcy is converted to cystathionine by cystathionine β-synthase and finally to cysteine using vitamin B6 as a cofactor (1). Therefore, plasma Hcy levels are determined ...

a pathway essential to many transmethylation reactions within the CNS, including the metabolism of neuroactive substances such as the monoamine neurotransmitters and melatonin; the formation of ...

These include methionine and the purine precursor ... act in the same way and fulfil functions as the TOR pathway, with its pleiotropic metabolic effects inhibiting cell proliferation but ...
