    regulatory mechanism

  • [protein|C239C155F5452C86BF6C78190BABBBB07A63DF87|BceR]: activation, [Pubmed|12890034], in [regulon|C239C155F5452C86BF6C78190BABBBB07A63DF87|BceR regulon]

    • regulation

  • induced in the presence of bacitracin, plectasin, mersacidin and actagardine, already at very low levels of bacitracin ([protein|search|BceR]) [Pubmed|12890034,26815905]
