WebCysteine is synthesized from methionine in four steps - the first two steps are part of the methionine cycle and the second two are part of the transsulfuration pathway. As described above in the methionine cycle, methionine gives rise to SAM, from which homocysteine is subsequently synthesized (Fig. 4 ). WebActs as a scavenger of glutamate in brain neuroprotection. The aspartate aminotransferase activity is involved in hepatic glucose synthesis during development and in adipocyte glyceroneogenesis. Using L-cysteine as substrate, regulates levels of mercaptopyruvate, an important source of hydrogen sulfide.
