Protein attributes

Sequence length	179 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis By similarity. Ref.6 Promotes caspase-independent apoptosis by regulating the function of two transcriptional regulators, AES and TLE1. Ref.6
Catalytic activity	N-substituted aminoacyl-tRNA + H2O = N-substituted amino acid + tRNA.
Subunit structure	Monomer.
Subcellular location	Mitochondrion.
Sequence similarities	Belongs to the PTH2 family.
