RL   Submitted (JAN-1999) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Trims short 3' overhangs of a variety of RNA species, leaving
CC       a one or two nucleotide 3' overhang. Responsible for the end-turnover
CC       of tRNA: specifically removes the terminal AMP residue from uncharged
CC       tRNA (tRNA-C-C-A). Also appears to be involved in tRNA biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00157}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00157}.
CC   -!- SIMILARITY: Belongs to the RNase T family. {ECO:0000255|HAMAP-
CC       Rule:MF_00157}.
