Abstract:The glmS ribozyme is predominantly present in gram-positive bacteria, and it is a riboswitch that inhibits the synthesis of glucosamine-6-phosphate. In addition, glmS riboswitch is a self-cleft ribozyme located in the 5' untranslated region of the glmS gene. Study on the structure and function of glmS riboswitch will be beneficial to develop new targets for antibiotic action. In this paper, we reviewed the structure and function of glmS riboswitch. In addition, we also introduce recent research progress and application of glmS riboswitch.
