Protein attributes

Sequence length	476 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the attachment of proline to tRNA(Pro) in a two-step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro) By similarity. HAMAP MF_01571
Catalytic activity	ATP + L-proline + tRNA(Pro) = AMP + diphosphate + L-prolyl-tRNA(Pro). HAMAP MF_01571
Subunit structure	Homodimer By similarity. HAMAP MF_01571
Subcellular location	Cytoplasm By similarity HAMAP MF_01571.
Domain	Consists of three domains: the N-terminal catalytic domain, the anticodon-binding domain and the C-terminal extension By similarity. HAMAP MF_01571
Sequence similarities	Belongs to the class-II aminoacyl-tRNA synthetase family. ProS type 3 subfamily.
