The present invention relates to a method for preparing a methionine analogue, comprising contacting a host cell with L-homoserine and one or more nucleophiles and cultivating said host cell and said one or more nucleophiles of (a) in a fermentation broth to produce said methionine analogue, wherein said host cell encodes and stably expresses a L-homoserine-O-acetyl- transferase (HSAT) and an O-acetyl-L-homoserine sulfhydrylase (OAHS). The present invention also relates to host cells encoding and expressing such HSAT and OAHS, as well as uses thereof for producing a methionine analogue.

The present invention relates to the field of pyrrolysyl-tRNA synthetases, their variants and uses thereof. Particularly, the present invention relates to variants (mutants) of parent pyrrolysyl-tRNA synthetases, wherein said variants have pyrrolysyl-tRNA synthetase activity and exhibit altered properties relative to the corresponding parent pyrrolysyl-tRNA synthetase.

The present invention provides methods for the non-enzymatic cleavage of target nucleic acids, for example for use in epigenomic and epitranscriptomic mapping and therapy. The method comprises contacting a target nucleic acid molecule with a bifunctional probe comprising a cleavage group and a covalent binding group such that the bifunctional probe covalently binds to the target nucleic acid molecule and cleaves the 5 target nucleic acid molecule bound thereto. Also provided is a method of selectively cleaving a target nucleic acid in a cell, a method for determining the modification of nucleic acid molecules by a nucleic acid modification enzyme in a cell, and a bifunctional probe for use in the methods.
