[Tryptophan 7-halogenase from Pseudomonas aureofaciens ACN strain: gene cloning and sequencing and the enzyme
Abstract:
The gene of tryptophan 7-halogenase was isolated from the Pseudomonas aureofaciens ACN strain producing pyrrolnitrin, a chlorocontaining antibiotic, and sequenced. A high homology degree (over 95%) was established for the genes and the corresponding halogenases from P. aureofaciens ACN and P. fluorescens BL915. The tryptophan 7-halogenase gene was amplified by PCR, and the corresponding enzyme was expressed in Escherichia coli cells using the pBSII SK+ vector.
