Product Description

Product Description

Se-containing proteins, generally understood as the misconception that only proteins containing selenocysteine residues are selenoproteins, or that selenoproteins only contain selenocysteine residues. In fact, only seletase is almost all selenoenzymes with selenosemiamino residues as the catalytic center, and not all selenoenzymes have catalytic functions. Therefore, strictly speaking, selenoproteins are mainly divided into the following two categories: selenocysteine-containing selenocysteine and selenothionine-containing selenothione.
