Amine-synthesizing enzyme N-substituted formamide deformylase: screening, purification, characterization, and gene cloning.

ABSTRACT: N-substituted formamide was produced through the hydration of an isonitrile by isonitrile hydratase in the isonitrile metabolism. The former compound was further degraded by a microorganism, strain F164, which was isolated from soil through an acclimatization culture. The N-substituted formamide-degrading microorganism was identified as Arthrobacter pascens. The microbial degradation was found to proceed through an enzymatic reaction, the N-substituted formamide being hydrolyzed to yield the corresponding amine and formate. The enzyme, designated as N-substituted formamide deformylase (NfdA), was purified and characterized. The native enzyme had a molecular mass of approximately 61 kDa and consisted of two identical subunits. It stoichiometrically catalyzed the hydrolysis of N-benzylformam
