Abstract: Methods for catalyzing C—H insertion reactions using heme enzymes are described. The present disclosure provides a method for producing a C—H insertion product comprising providing an substrate having an sp3-hybridized C—H bond, a carbene precursor such as a diazo reagent, and a heme enzyme, and admixing the components in a reaction for a time sufficient to produce the C—H insertion product. Heme enzyme variants useful for carrying out in vivo and in vitro C—H insertion reactions, as well as expression vectors and host cells expressing the heme enzymes, are also described.

Abstract: A media file presentation method is disclosed, applicable to an application client and performed at a computing device. The computing device performs a blocking operation on a process of switching from a background state to a suspended state and covers a page screenshot by using a to-be-presented media file in the process of switching from the background state to the suspended state, the page screenshot being captured in a process of switching from a foreground state to the background state. Finally, the computing device presents the media file covering the page screenshot in a process of switching from the suspended state to the foreground state.
