Function

function

Essential for tRNA splicing and maturation. Acts by directly joining spliced tRNA halves to mature-sized tRNAs. Joins RNA with 2',3'-cyclic-phosphate or 3'-phosphate ends to RNA with 5'-hydroxy ends.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.
