Directed selection of differentiation mutants of Streptomyces noursei using chemostat cultivation.

abstract：:The gene mak1FN coding for maltokinase from Actinoplanes missouriensis is located in a cluster similar to glycogen metabolism clusters identified in Streptomyces coelicolor. Sequence comparisons demonstrate that mak1-related genes coding for homologous proteins are present in many bacterial genomes including taxonomic...
