FIGURE 5.

Mating efficiencies of H. volcanii cells presenting WT glycosylation with ΔaglBΔagl15 cells. A comparison of cell fusion efficiencies between WT glycosylation strains and strains lacking enzymes that respectively mediate or contribute to the attachment of the pentasaccharide and the low salt tetrasaccharide to the S-layer glycoprotein. The salinity used was 3.4 M NaCl. In each column, the horizontal line corresponds to the mean. In addition, different samples were compared by a one-sided Mann–Whitney U test. The p-value is provided in each case.
