Abstract
Recent genetic and biochemical experiments have revealed the existence of at least seven different sigma factors in Streptomyces coelicolor and demonstrated a role for alternative sigma factors in the control of differentiation and also in the transcription of primary metabolic genes. S. coelicolor has four genes predicted to encode sigma factors that are very closely related to the sigma 70 polypeptide of Escherichia coli.
摘要
最近的遗传学和生物化学实验表明，天蓝色链霉菌中至少存在七种不同的σ因子，并证明了替代σ因子在分化控制以及初级代谢基因转录中的作用。天蓝色链霉菌有四个基因，预测其编码的σ因子与大肠杆菌的σ70多肽密切相关。
