摘要: Brassica oleracea deoxycytidine deaminase (BoDCD), a (DCD, EC 3.5.4.14) enzyme, is known to play an important role in the Trichoderma harzianum ETS 323 mediated resistance mechanism young leaves of B. var. capitata during Rhizoctonia solani infection. BoDCD potentially neutralizes cytotoxic products host lipoxygenase activity, and thereby restricts hypersensitivity-related programmed cell death induced plants initial stages To determine biochemical characteristics partially elucidate designated functional properties BoDCD, enzyme was cloned into Escherichia coli expression system, its potential neutralize toxic analogues 2′-deoxycytidine (dC) examined. transformants E. cells were found be resistant at all concentrations tested. The also overexpressed as histidine-tagged protein purified using nickel chelating af...
