Popis: A new strategy for molecular cloning in the cyanobacterium Anacystis nidulans R-2 is described. This strategy involved the use of a transposon and was developed for the cloning of a gene encoding methionine biosynthesis. A met::Tn 901 mutant was isolated. Chromosomal DNA fragments were cloned in the Escherichia coli plasmid vector pACYC184. A recombinant plasmid carrying the inactivated met::1n901 gene was selected after transformation to E. coli. The cloned met::Tn901 DNA fragment was used as a probe to select the corresponding A. nidulans R-2 wild-type met gene from a gene library prepared in E. coli, using the newly constructed shuttle cosmid vector pPUC29. When transformed into A. nidulans Met mutants, this cloned gene allowed the mutants to grow prototrophically.
