conversion of seryl-tRNAsec to selenocys-tRNAsec obsolete selenocysteinyl-tRNA(Sec) biosynthetic process https://github.com/geneontology/go-ontology/issues/24381 https://github.com/geneontology/go-ontology/issues/8685 true selenocysteinyl-tRNA(Sec) formation pr biological_process GO:0097056 This term was obsoleted because it is the same process as GO:0001717 conversion of seryl-tRNAsec to selenocys-tRNAsec. OBSOLETE. The chemical reactions and pathways resulting in the formation of selenocysteinyl-tRNA(Sec). This process occurs through the following steps: a unique serine-tRNA with a UGA recognizing anticodon is first aminoacylated with serine; this is then phosphorylated by phosphoseryl-tRNA[Ser]Sec kinase; lastly, selenium is swapped for the phosphate on the serine. 2011-05-25T05:33:19Z selenocysteinyl-tRNA(Sec) biosynthesis selenocysteinyl-tRNA(Sec) synthesis selenocysteinyl-tRNA(Sec) anabolism
