multisynthetase complex

Function

• synthesis of aminoacyl-tRNAs
• multisubunit complex that groups tRNA ligases for Arg, Asp, Glu, Gln, Ile, Leu, Lys, Met & Pro

Structure

• consists of:
  • bifunctional glutamyl-prolyl-tRNA synthetase
  • monospecific
    • isoleucyl tRNA synthetase
    • leucyl RNA tsynthetase
    • glutaminyl tRNA synthetase
    • methionyl tRNA synthetase
    • lysyl tRNA synthetase
    • arginyl tRNA synthetase aspartyl-tRNA synthetases
• auxiliary proteins, p18, p48, p43, JTV1 (p38)

More general terms

• molecular complex
• amino acyl tRNA synthetase
