Crystal structure of human mitochondrial tyrosyl-tRNA synthetase in complex with an adenylate analog
Template:ABSTRACT PUBMED 17997975
Disease
[SYYM_HUMAN] Defects in YARS2 are the cause of myopathy with lactic acidosis and sideroblastic anemia type 2 (MLASA2) [MIM:613561]. MLASA2 is a rare oxidative phosphorylation disorder specific to skeletal muscle and bone marrow. Affected individuals manifest sideroblastic anemia, progressive lethargy, muscle weakness, and exercise intolerance associated with persistent lactic acidemia.[1][2]
Function
[SYYM_HUMAN] Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two-step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr) (By similarity).[3]
About this Structure
2pid is a 2 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
