ENZYME entry: EC 6.1.1.26
Accepted Name |
Pyrrolysine--tRNA(Pyl) ligase.
|
Alternative Name(s) |
PylRS. |
Pyrrolysyl-tRNA synthetase. |
Reaction catalysed |
ATP + L-pyrrolysine + tRNA(Pyl) <=> AMP + diphosphate + L-pyrrolysyl-tRNA(Pyl) |
Comment(s) |
- 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.
