The protein

Basic information/ Evolution

• Catalyzed reaction/ biological activity:
  • conversion of L-threonine, bicarbonate/CO2 and ATP to give the intermediate L-threonylcarbamoyl-AMP (TC-AMP) and pyrophosphate as products PubMed
  • biosynthesis of the hypermodified base threonylcarbamoyladenosine (t(6)A), a universal modification found at position 37 of ANN decoding tRNAs, which imparts a unique structure to the anticodon loop enhancing its binding to ribosomes in vitro (shown for the corresponding E. coli protein YrdC) PubMed
