Similarity and difference of organizations of streptomycetic landomycins clusters

Aim. The aim of the work is to establish level similarity primary structure and organization landomycin clusters streptomycetes. Methods. Information on nucleotide sequences annotations streptomycetic biosynthesis genes AF080235,1, KJ645792.1, HQ828984.1 genomes strains S. cyanogenus S136, globisporus 1912-4Crt freely available in GenBank. Analysis streptomycetes was performed using program BLASTN from server NSBI. Results. remote localization a number probable lan-cluster (prx, lanW, lanYR) has been established. similar lndU / lanU lndY lanY genes, which are not necessary for biosynthesis, have shown be least similar. It that S136 expected localized outside cortical region chromosome strain. Landomycin-producing isolated soil samples different ecological niches continents planet. Conclusions. difference lan- lnd-clusters expressed lanYR).
