Pyrrolysine--tRNA(Pyl) ligase.
based on mapping to UniProt Q8PWY1
ATP + L-pyrrolysine + tRNA(Pyl) = AMP + diphosphate + L-pyrrolysyl- tRNA(Pyl).
-!- In organisms such as Methanosarcina barkeri that incorporate the modified amino acid pyrrolysine (Pyl) into certain methylamine methyltransferases, an unusual tRNA(Pyl), with a CUA anticodon, can be charged directly with pyrrolysine by this class II aminoacyl- -tRNA ligase. -!- Specific for pyrrolysine as substrate as it cannot be replaced by lysine or any of the other natural amino acids.
