Selenocysteine synthase (SecS) converts phospho-seryl-tRNA into selenocysteinyl-tRNA using selenophosphate as the Se donor[1].

Updated on 24-August-2016

3bc8, 3bca - mSecS elastase-resistant fragment - mouse

3bcb - mSecS elastase-resistant fragment + phosphate

2z67 - SecS - Methanococcus maripaludis

3hl2 - SecS + tRNASec - human
3w1i – AaSecS + pyridine derivative – Aquifex aeolicus
3wcn – AaSecS (mutant)
3w1h, 3wco – AaSecS (mutant) + pyridine derivative
3w1j – AaSecS + pyridine derivative
3w1k – AaSecS (mutant) + pyridine derivative + tRNASec
