SEPSECS( Human )
Sep (O-phosphoserine) tRNA:Sec (selenocysteine) tRNA synthase
Alias
PCH2D|SLA|SLA/LP
The amino acid selenocysteine is the only amino acid that does not have its own tRNA synthetase. Instead, this amino acid is synthesized on its cognate tRNA in a three step process. The protein encoded by this gene catalyzes the third step in the process, the conversion of O-phosphoseryl-tRNA(Sec) to selenocysteinyl-tRNA(Sec).[provided by RefSeq, Mar 2011].
