Additionally, 11 conserved signature proteins have been identified which are found in all sequenced Streptomyces species and K. setae. These proteins are believed to be unique to the Streptomycetales order, thus provide molecular markers which can be used to distinguish this group from the rest of the Actinomycetota.
Streptomyces is the largest genus of Actinomycetota, and the type genus of the family Streptomycetaceae. [3] Over 700 species of Streptomyces bacteria have been described. [ 4 ] [ 5 ] [ 6 ] As with the other Actinomycetota, streptomycetes are gram-positive , and have very large genomes with high GC content .
The following is a list of Streptomyces species, organized alphabetically by species name. [1] Names that have not been validated according to the Bacteriological Code are enclosed in "quotes". As of June 2021 [update] , there are 679 valid species of Streptomyces and an additional 121 provisional species. [ 1 ]
