Citoplazmatska triptofanil-tRNK sintetaza je enzim koji je kosd ljudi kodiran genom WARS.^[1]^[2]^[3]

Aminoacil-tRNK sintetaze kataliziraju aminoacilaciju tRNK pomoću njihove srodne aminokiseline. Zbog njihove središnje uloge u povezivanju aminokiselina s nukleotidnim tripletima sadržanim u tRNK, smatra se da su aminoacil-tRNK sintetaza među prvim proteinima, koje su se pojavile u evoluciji. Postoje dva oblika triptofanil-tRNA sintetaze, citoplazmatski oblik, zvani WARS i mitohondrijski oblik, zvani WARS2. Triptofanil-tRNA sintetaza (WARS) katalizira aminoacilaciju tRNK (trp) sa triptofanom i indukuje je interferon. Triptofanil-tRNA sintetaza pripada porodici tRNK-sintetaza klase I. Za ovaj gen pronađene su četiri varijante transkripta koje kodiraju dvije različite izoforme.^[3]

Aminokiselinska sekvenca

Dužina polipeptidnog lanca je 471 aminokiselina, a molekulska težina 53.165 Da.^[4]
