Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.

This report details the discovery and characterization of a versatile bacterial cytochrome P450, NzeB, which catalyzes the dimerization of diketopiperazines via enzymatic C–H functionalization. This includes the first high-resolution crystal structure of a diketopiperazine dimerase, which along with active site via mutagenesis and quantum mechanical calculations, provides insight into the selectivity and mechanism of these enzymes.
