POSITION AND FUNCTION OF THE ORGANIC SELENIUM IN GLUTATHIONE PEROXIDASE |
|
| Abstract: | The forms in which selenium serves in erythrocyte glutathione peroxidase have been further identified. The tertiary structure suggests how selenocysteine and other amino acid residues function together at the enzyme active site. |
| Keywords: | amino acid sequence mass spectrometry reactive site selenocysteine tertiary protein structure oxidized and reduced enzyme X-ray diffraction |
