Common Name Selenocystathionine
Description Selenocystathionine is formed from Selenohomocysteine by the enzyme cystathionine beta-synthase (EC 4.2.1.22), as a by-product of cystathionine synthesis. Selenocystathionine is consumed in the diet, and is one of the main compounds present in plants that tend to hyperaccumulate selenium and use it as an elemental plant defense mechanism.

Enzyme 1 General Function Inorganic ion transport and metabolism
Enzyme 1 Specific Function Bifunctional enzyme with both ATP sulfurylase and APS kinase activity, which mediates two steps in the sulfate activation pathway. The first step is the transfer of a sulfate group to ATP to yield adenosine 5'-phosphosulfate (APS), and the second step is the transfer of a phosphate group from ATP to APS yielding 3'-phosphoadenylylsulfate (PAPS:activated sulfate donor used by sulfotransferase). In mammals, PAPS is the sole source of sulfate; APS appears to be only an intermediate in the sulfate- activation pathway. May have a important role in skeletogenesis during postnatal growth
