Mechanistic characterization of N-formimino-L-glutamate iminohydrolase from Pseudomonas aeruginosa.

Abstract excerpt

N-Formimino-l-glutamate iminohydrolase (HutF) from Pseudomonas aeruginosa catalyzes the deimination of N-formimino-l-glutamate in the histidine degradation pathway. An amino acid sequence alignment between HutF and members of the amidohydrolase superfamily containing mononuclear metal centers indicated that residues Glu-235, His-269, and Asp-320 are involved in substrate binding and activation of the nucleophilic...
