malfunction
malfunction
cells deleted of HVO_1799 fail to fully reduce the isoprene chains of membrane phospholipids and glycolipids. The absence of HVO_1799 leads to a loss of saturation of the omega-position isoprene subunit of C55 and C60 dolichol phosphate, with the effect of HVO_1799 deletion being more pronounced with C60 dolichol phosphate than with C55 dolichol phosphate. Glycosylation of dolichol phosphate in the deletion strain occurred preferentially on that version of the lipid saturated at both the alpha- and omega-position isoprene subunits
