Description

Ketoamine Oxidase is a highly specific oxidative enzyme that catalyzes the conversion of ketoamine substrates with excellent activity and selectivity. Its robust stability, broad substrate tolerance, and compatibility with mild reaction conditions make it a valuable tool for biochemical studies, pathway elucidation, and biocatalytic method development. The enzyme supports applications in metabolic research, analytical assays, and the synthesis of structurally defined intermediates.
