General annotation (Comments)

Function

Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L-seryl-tRNA(Sec), which will be further converted into selenocysteinyl-tRNA(Sec) By similarity. HAMAP-Rule MF_00176

Catalytic activity

ATP + L-serine + tRNA(Ser) = AMP + diphosphate + L-seryl-tRNA(Ser). HAMAP-Rule MF_00176

ATP + L-serine + tRNA(Sec) = AMP + diphosphate + L-seryl-tRNA(Sec). HAMAP-Rule MF_00176

Pathway

Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec) biosynthesis; L-seryl-tRNA(Sec) from L-serine and tRNA(Sec): step 1/1. HAMAP-Rule MF_00176

Subunit structure

Homodimer. The tRNA molecule binds across the dimer By similarity.

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00176.

Domain

Consists of two distinct domains, a catalytic core and a N-terminal extension that is involved in tRNA binding By similarity. HAMAP-Rule MF_00176

Sequence similarities

Belongs to the class-II aminoacyl-tRNA synthetase family. Type-1 seryl-tRNA synthetase subfamily.
