Taxonomic identifier

269797 [NCBI]

Taxonomic lineage

Archaea › Euryarchaeota › Methanomicrobia › Methanosarcinales › Methanosarcinaceae › Methanosarcina

Protein attributes

Sequence length	419 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the attachment of pyrrolysine to tRNA(Pyl). Pyrrolysine is a lysine derivative encoded by the termination codon UAG. Ref.2
Catalytic activity	ATP + L-pyrrolysine + tRNA(Pyl) = AMP + diphosphate + L-pyrrolysyl-tRNA(Pyl). HAMAP MF_01573
Subcellular location	Cytoplasm. HAMAP MF_01573
Sequence similarities	Belongs to the class-II aminoacyl-tRNA synthetase family.
