Hansenula holstii

Hansenula holstii NCYC 560 produces cell-wall, and exocellular, phosphorylated mannans of mol. wt. 10°. The cell-wall mannan contains two branched polysaccharides having (l- 2) and (1— 3) linkages, with /3-d, in addition to a-D, linkages. Phosphoric diesters are present. The exocellular phosphonomannan is composed of 3 polymers, each... [Pg.85]

Bretthauer and coworkers isolated from Hansenula holstii a particulate enzyme capable of catalyzing the transfer of D-man-nose- C from GDP-D-mannose- C to endogenous, mannan-acceptor molecules. The same particulate enzyme fraction was found to catalyze the transfer of phosphate- from GDP- P-D-mannose to endogenous mannan. Divalent-metal ions proved to be required, Mn + being the most eflFective for transfer of phosphate- and D-mannose- C. The incorporation of both phosphate- and D-mannose- C was inhibited to the extent of 70% by either 0.5 mM GMP or GDP. [Pg.398]

Inhibition by 2-deoxy-D-arai>mn-hexose of the biosynthesis of the cell-wall mannan in Saccharomyces cerevisiae appears to involve a complex mechanism that disrupts the synthesis of protein rather than glycosylation. Studies using a particulate enzyme from Mycobacterium smegmatis have demonstrated that polyisoprenyl D-mannosyl phosphates are obligatory donors, while preparations obtained from Hansenula holstii have shown that a D-mannosyl-lipid is involved in the synthesis of mannosylated serine (or threonine) residues. ... [Pg.324]
