Compilation and analysis of DNA sequences associated with apparent streptomycete promoters

Nucleic Acids Res. 1992 Mar 11;20(5):961-74. doi: 10.1093/nar/20.5.961.


The DNA sequences associated with 139 apparent streptomycete transcriptional start sites are compiled and compared. Of these, 29 promoters appeared to belong to a group which are similar to those recognized by eubacterial RNA polymerases containing sigma 70-like subunits. The other 110 putative promoter regions contain a wide diversity of sequences; several of these promoters have obvious sequence similarities in the -10 and/or -35 regions. The apparent Shine-Dalgarno regions of 44 streptomycete genes are also examined and compared. These were found to have a wide range of degree of complementarity to the 3' end of streptomycete 16S rRNA. Eleven streptomycete genes are described and compared in which transcription and translation are proposed to be initiated from the same or nearby nucleotide. An updated consensus sequence for the E sigma 70-like promoters is proposed and a potential group of promoter sequences containing guanine-rich -35 regions also is identified.
