Complete genome sequence of Streptomyces ambofaciens ATCC 23877, the spiramycin producer.

Streptomyces ambofaciens ATCC23877 is a soil bacterium industrially exploited for the production of the macrolide spiramycin which is used in human medicine as an antibacterial and anti-toxoplasmosis chemical. Its genome consists of a 8.3 Mbp linear chromosome and a 89 kb circular plasmid. The complete genome sequence reported here will enable us to investigate Streptomyces genome evolution and to discover new secondary metabolites with potential applications notably in human medicine.
