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.

Catalytic activity

ATP + L-serine + tRNA(Ser) = AMP + diphosphate + L-seryl-tRNA(Ser). HAMAP MF_01278

ATP + L-serine + tRNA(Sec) = AMP + diphosphate + L-seryl-tRNA(Sec). HAMAP MF_01278

Cofactor

Binds 1 Zn2+ ion per subunit. This ion is coordinated with 2 cysteines, 1 glutamate and a water molecule that dissociates from the zinc ion to allow the coordination of the amino group of the serine substrate, which is essential for catalysis By similarity.

Pathway

Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec) biosynthesis; L-seryl-tRNA(Sec) from L-serine and tRNA(Sec): step 1/1. HAMAP MF_01278

Subunit structure

Homodimer By similarity.

Subcellular location

Cytoplasm By similarity.

Domain

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

Sequence similarities

Belongs to the class-II aminoacyl-tRNA synthetase family. Type-2 seryl-tRNA synthetase subfamily.
