Evolutionary Basis for the Use of Selenocysteine
2011Evolutionary adaptations to dietary selenium may explain the use of selenocysteine in proteins. If so, adaptive signals should be present in the genomic regions of selenoprotein genes. It is, however, difficult to identify the signatures of adaptation left by natural selection in the genome of extant species (including humans).

Common modifications of selenocysteine in selenoproteins
Essays in Biochemistry, 2019Abstract Selenocysteine (Sec), the sulfur-to-selenium substituted variant of cysteine (Cys), is the defining entity of selenoproteins. These are naturally expressed in many diverse organisms and constitute a unique class of proteins.

Occurrence and characterization of selenocysteine in proteins
1984Publisher Summary This chapter focuses on the occurrence and characterization of selenocysteine in proteins. Four selenium-dependent enzymes that contain essential selenium in the form of selenocysteine residues have been identified to date. Three of these are of bacterial origin—glycine reductase, certain formate dehydrogenases, and α hydrogenase ...
