Abstract: The present invention relates to a method for producing a conjugate of two substrates, the method comprising the steps of (a) providing two substrates, each substrate being independently selected from the one or more of the groups consisting of small molecules, and proteins, and (b) enzymatically conjugating the two substrates using a sortase F enzyme, or a catalytic domain thereof. One substrate comprises a sortase F recognition motif, while the other substrate comprises at least one motif selected from a Glyn motif, an Alan motif, or a motif consisting of a mixture of Ala and Gly residues the motif totaling n residues, where n is an integer from ?1 to ?21. The reaction takes place in an aqueous reaction medium comprising a salt concentration of from about ?0.01 to ?3 M, thereby producing a conjugated product of the two substrates.
