Probable bifunctional tRNA threonylcarbamoyladenosine biosynthesis protein (IPR009220)

Short name: tRNA_threonyl_synthase/kinase

Family relationships

Description

This entry describes a probable bifunctional tRNA threonylcarbamoyladenosine biosynthesis protein. Its N-termanal domain is homologous to the Kae1/YgjD family, which is involved in tRNA threonylcarbamoyladenosine biosynthesis [PMID: 21285948]. Its C-terminal region contains a serine/threonine protein kinase domain (STYKS) and is homologous to Bud32. Kae1 and Bud32 are two components of the the KEOPS/EKC complex, which has been implicated in transcription, telomere maintenance and chromosome segregation [PMID: 21183954]. In this archaeal family, it seems that the Kae1 and Bud32 orthologues are fused.
