Coagulase expression in Staphylococcus aureus is positively and negatively modulated by an agr-dependent mechanism

J Bacteriol. 1994 Sep;176(17):5534-6. doi: 10.1128/jb.176.17.5534-5536.1994.

Abstract

Expression of staphylocoagulase by agr+ Staphylococcus aureus depends on the growth phase, being maximal during exponential growth and decreasing sharply postexponentially, while an agr-deleted strain continuously expresses an intermediate level of coagulase. Therefore, coagulase expression appears to be both positively and negatively modulated by an agr-dependent mechanism.
