Several studies evidenced their implication in the host–pathogeninteraction and virulence mechanisms. In the present study, we characterized the in vitro activity ofCaBmt3, aβ-1,2-mannosyltransferase involved in the elongation ofβ-1,2-oligomannosides oligo-mers onto the cell-wall polymannosylatedN-glycans. A recombinant soluble enzyme Bmt3p wasproduced inPichia pastorisand its enzyme activity was investigated using natural and synthetic oli-gomannosides as potential acceptor substrates. Bmt3p was shown to exhibit an exquisite enzymaticspecificity by adding a single terminalβ-mannosyl residue toα-1,2-linked oligomannosides cappedby a Manβ1–2Man motif. Furthermore, we demonstrated that the previously identified CaBmt1 andCaBmt3 efficiently act together to generate Manβ1-2Manβ1–2[Manα1–2]nsequence fromα-1,2-linkedoligomannosides onto exogenous and endogenous substrates.Show less >
