Application

EC Number Application Comment Organism
4.2.1.49 medicine L70P and R450C mutations in the coding region of the UROC1 gene in a girl with urocanic aciduria presenting with mental retardation and intermittent ataxia. Both mutations cannot produce a fully functional enzyme, L70P substitution implies the disruption of an alpha-helix in the N-terminus, which alters its properties and therefore, its function. The R450C change renders impossible any interaction between urocanase and its substrate and loses its enzyme activity Homo sapiens

Cloned(Commentary)

EC Number Cloned (Comment) Organism
4.2.1.49 UROC1 gene cloned into the expression vector pET100/D-TOPO with an N-terminal tag containing the Xpress epitope and a 6xHis-tag. Expressed in Escherichia coli BL21Start (D3) Homo sapiens
