Tryptophanyl-tRNA synthetase, cytoplasmic is an aminoacyl-tRNA synthetase enzyme that attaches the amino acid tryptophan to its cognate tRNA. In humans, it is encoded by the WARS gene. [5] [6] [7]

Two forms of tryptophanyl-tRNA synthetase exist, a cytoplasmic form, named WARS, and a mitochondrial form, named WARS2. Tryptophanyl-tRNA synthetase (WARS) catalyzes the aminoacylation of tRNA(trp) with tryptophan and is induced by interferon. Tryptophanyl-tRNA synthetase belongs to the class I tRNA synthetase family. Four transcript variants encoding two different isoforms have been found for this gene. [7]

Phenylalanine Incorporation

Although WARS1 classically aminoacylates tryptophan, during states tryptophan depeletion, this enzyme has been observed to activate both tryptophan and phenylalanine [8] .

Aminoacyl tRNA synthetase

An aminoacyl-tRNA synthetase, also called tRNA-ligase, is an enzyme that attaches the appropriate amino acid onto its corresponding tRNA. It does so by catalyzing the transesterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA. In humans, the 20 different types of aa-tRNA are made by the 20 different aminoacyl-tRNA synthetases, one for each amino acid of the genetic code.

WHEP-TRS protein domain

In molecular biology, the protein domain WHEP-TRS refers to helix-turn-helix domains. They are found in variable numbers in a particularly common protein, named, glutamyl-prolyl tRNA synthetase(EPRS). This protein domain has an important function in protein–protein interactions between synthetases. WHEP domains exhibit high-affinity interactions with tRNA, indicating a putative evolutionary relationship to facilitate tRNA binding to fused synthetases, thereby enhancing catalytic efficiency.
