... substrate binding process. This provides strong evidence that N-glycans, in particular their terminal structures, are involved in regulating the GABA translocation of GAT1, but not in binding of GAT1 ... half-life of DDQ containing all three N-glycosylation mutations was reduced even more, compared with that of DDN, showing a value of only 5.5 h. In contrast, the stability...
