DrugBank target: P14868 (SYDC_HUMAN)     

Example structure of target: 4j15

( There is one structure corresponding to this UniProt sequence in the PDB. )

Aspartate--tRNA ligase, cytoplasmic

Aspartyl-tRNA synthetase, Cell proliferation-inducing gene 40 protein, AspRS.


Catalyzes the specific attachment of an amino acid to its cognate tRNA in a 2 step reaction: the amino acid (AA) is first activated by ATP to form AA-AMP and then transferred to the acceptor end of the tRNA..

Enzyme   [EC->PDB]   [IntEnz]   [ExPASy]   [KEGG]  

Catalytic activity

ATP + L-aspartate + tRNA(Asp) = AMP + diphosphate + L-aspartyl-tRNA(Asp).


Hypomyelination with brainstem and spinal cord involvement and leg spasticity (HBSL) [MIM:615281]: An autosomal recessive leukoencephalopathy characterized by onset in the first year of life of severe spasticity, mainly affecting the lower limbs and resulting in an inability to achieve independent ambulation. Affected individuals show delayed motor development and nystagmus; some may have mild mental retardation. Brain MRI shows hypomyelination and white matter lesions in the cerebrum, brainstem, cerebellum, and spinal cord. {ECO:0000269|PubMed:23643384}. Note=The disease is caused by mutations affecting the gene represented in this entry.
