Disclosed herein are methods for the selective substitution of a hydrogen bonded to a carbon atom (e.g., a hydrogen of an aliphatic methylene group) of a compound, which comprise contacting the compound with a substituent in the presence of a BesD halogenase.

The present invention concerns new thiolysine and selenolysine compounds that can be used as building blocks for peptides and proteins, providing ligation handles for site- and chemoselective modification of said peptides and proteins. In particular, the invention provides. In particular, the invention provides (the use of) the compounds 5-thiolysine (also referred to as δ-thiolysine); 4-thiolysine (also referred to as γ-thiolysine); 5-selenolysine (also referred to as δ-selenolysine) and 4-selenolysine (also referred to as γ-selenolysine). The positioning of the thiol or selenol group at the respective carbon atom allows for a very efficient intramolecular transfer reaction to take place after conjugation with a selected ligand, and the thiol or selenol group may subsequently be removed using reported procedures, thereby restoring the native lysine structure, or be used as an additional conjugation handle. The methodology is fast and gives well-defined material.

The present invention relates to the field of total chemical synthesis of ubiquitin and related peptides. More in particular, a method is provided of solid phase synthesis of ubiquitin, ubiquitin mutants and derivatives thereof. It was the object of the present invention to provide an approach for the total chemical synthesis of ubuiqitin, which allows for the chemical synthesis of virtually any Ub mutant and giving high overall efficiency and purity. The present inventors have surprisingly found that this object can be realized with a method relying on incorporation of special amino acid building blocks. This approach was found to allow for exceptionally high yields of up to 14% and to provide an synthetic entry into virtually any ubiquitin derivative.
