Nmannosylation
Nmannosylation is a type of post-translational modification that occurs in various organisms, including bacteria, archaea, and eukaryotes. It involves the enzymatic attachment of a mannose sugar residue to a nitrogen atom, typically on an asparagine side chain within a protein. This process is distinct from N-glycosylation, which involves the transfer of a larger oligosaccharide to asparagine. In Nmannosylation, a single mannose unit is added.
The enzymes responsible for Nmannosylation are known as Nmannosyltransferases. These enzymes play a crucial role in
