InterPro domain: IPR040598

Protein KD93 is a NIP7 homologue and belongs to the UPF0113 family. The overall fold of KD93 consists of two interlinked alpha/beta domains. The C-terminal domain resembles the PUA domain of some RNA modification enzymes, especially that of archaeosine tRNA-ribosyltransferase (ArcTGT), suggesting a possible molecular function related to RNA binding [ 1 ]. This entry represents the N-terminal, pre-PUA domain.
