Ligands: GOL, K, PO4, SO4, TYR Related: 4q93 Activity: Tyrosine--tRNA ligase, with EC number 6.1.1.1 Resources: FirstGlance, OCA, RCSB, PDBsum Disease [SYYC_HUMAN] Defects in YARS are the cause of Charcot-Marie-Tooth disease dominant intermediate type C (CMTDIC) [MIM:608323]. CMTDIC is a form of Charcot-Marie-Tooth disease characterized by clinical and pathologic features intermediate between demyelinating and axonal peripheral neuropathies, and motor median nerve conduction velocities ranging from 25 to 45 m/sec. Function [SYYC_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).
