This research aims to characterize the tRNA-specific adenosine deaminase and its role in modifying tRNA.
Described the functions of the heterodimeric enzyme from Saccharomyces cerevisiae.
Identified essential genes (TAD2 and TAD3) encoding the enzyme subunits.
Analyzed the evolutionary relationship between the CDA superfamily and RNA-dependent adenosine deaminases.
The enzyme generates inosine (I) at position 34 of tRNAs, essential for elongating tRNAs.
Both subunits of the enzyme contain CDA motifs and are required for tRNA modification.
Results establish a link between the CDA superfamily and RNA-dependent adenosine deaminases.
