  • Method for producing compound containing heterocycle
    Patent number: 10329558
    Abstract: An object of the present invention is to provide a method of stably introducing a heterocycle into a substrate peptide by using an azoline backbone introducing enzyme. The present invention provides a method of introducing a heterocycle into a leader-sequence-free substrate peptide by using an azoline backbone introducing enzyme to which a leader sequence of the substrate has been bound.
