Figure 2From: The acquisition of novel N-glycosylation sites in conserved proteins during human evolution Timing of acquisition and numbers of novel N-glycosylation sites in the human lineage. Numbers of novel N-glycosylation sites acquired in the human lineage of the mammalian phylogenetic tree are shown. The number of sites acquired is shown on each branch where the N-glycosylation site consensus motif emerged in the ancestor of the corresponding clade.Back to article page
