The gene encoding RNase III in Streptomyces coelicolor is transcribed during exponential phase and is required for antibiotic production and for proper sporulation.
Phenotypic analysis of a constructed RNase III null mutant of Streptomyces coelicolor revealed that RNase III is required for both antibiotic production and proper formation of sporulation septa. Transcriptional analysis of the gene encoding RNase III indicated that it is transcribed exclusively during exponential phase as part of a tricistronic message.
