Probable tRNA N6-adenosine threonylcarbamoyltransferase (OSGEP)

Part of the EKC/KEOPS complex that's necessary for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons starting with adenine. The complex is probably involved in the transfer of this threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37.

OSGEP probably plays a direct catalytic role in this reaction, but requires other protein(s) of the complex to fulfill this activity. .
